Mr. Trump Alone Can Order a Nuclear Strike. Congress Can Change That.

The broad debate over President Trump’s fitness for the difficult and demanding office he holds has recently been reframed in a more pointed and urgent way: Does he understand, and can he responsibly manage, the most destructive nuclear arsenal on earth?
The question arises for several reasons. He has threatened to “totally destroy” North Korea. He has reportedly pressed for a massive buildup in the American nuclear arsenal, which already contains too many — 4,000 — warheads. And soon he will decide whether to sustain or set a course to possibly unravel the immensely important Iran nuclear deal.
Doubts about his competency were reinforced this week by Senator Bob Corker, who charged that Mr. Trump was treating his office like “a reality show” with reckless threats that could set the nation “on the path to World War III.” Mr. Corker, a Republican from Tennessee, says he is relying on Secretary of State Rex Tillerson, Defense Secretary Jim Mattis and John Kelly, the White House chief of staff, to help “separate our country from chaos.” That is a searing indictment, and Mr. Corker is no garden-variety legislator; as chairman of the Senate Foreign Relations Committee, he is a respected, and largely responsible, voice on national security issues.
Further, NBC News now reports that Mr. Tillerson judged Mr. Trump a “moron” after a July 20 meeting in which Mr. Trump, apparently distressed that the arsenal has declined since the Cold War, said he wanted a nearly tenfold increase in weapons.
Mr. Trump’s policy pronouncements during the campaign betrayed either profound ignorance or dangerous nonchalance: At one point he wondered why America had nuclear weapons if it didn’t use them; at another he suggested that Japan and South Korea, which have long lived under the American security umbrella, should develop their own nuclear weapons. But nothing he said has been quite as unsettling as his recent tweetstorms about North Korea, his warnings of “fire and fury” and his quip about “the calm before the storm.”

The U.S. Nuclear Arsenal Is Already Too Big

President Trump believes the U.S. needs more weapons, but its current stockpile of 4,000 could decimate much of the planet.
Each bomb
equals five
warheads
A New York Times analysis found the U.S. could use 1,103 nuclear warheads and decimate China, Russia, North Korea, Iran, Libya, Iraq, and Syria...
... and still have 2,897 left.
Many have hoped, and still hope, that Mr. Trump’s aggressive posture is mostly theater, designed to slake his thirst for attention, keep adversaries off guard and force changes in their behavior by words alone. But there is no underlying strategy to his loose talk, and whatever he means by it, Congress has been sufficiently alarmed to consider legislation that would bar the president from launching a first nuclear strike without a declaration of war by Congress. It wouldn’t take away the president’s ability to defend the country.
That’s a sound idea, and could be made stronger with a requirement that the secretaries of defense and state also approve any such decision. As things stand now, the Atomic Energy Act of 1946, passed when there was more concern about trigger-happy generals than elected civilian leaders, gives the president sole control. He could unleash the apocalyptic force of the American nuclear arsenal by his word alone, and within minutes.

How Russia Harvested American Rage to Reshape U.S. Politics

YouTube videos of police beatings on American streets. A widely circulated internet hoax about Muslim men in Michigan collecting welfare for multiple wives. A local news story about two veterans brutally mugged on a freezing winter night.
All of these were recorded, posted or written by Americans. Yet all ended up becoming grist for a network of Facebook pages linked to a shadowy Russian company that has carried out propaganda campaigns for the Kremlin, and which is now believed to be at the center of a far-reaching Russian program to influence the 2016 presidential election.
A New York Times examination of hundreds of those posts shows that one of the most powerful weapons that Russian agents used to reshape American politics was the anger, passion and misinformation that real Americans were broadcasting across social media platforms.
The Russian pages — with names like “Being Patriotic,” “Secured Borders” and “Blacktivist” — cribbed complaints about federal agents from one conservative website, and a gauzy article about a veteran who became an entrepreneur from People magazine. They took descriptions and videos of police beatings from genuine YouTube and Facebook accounts and reposted them, sometimes lightly edited for maximum effect.
Other posts on the Russian pages used stilted language or phrases rarely found in American English. Yet their use of borrowed ideas and arguments from Americans, which were already resonating among conservatives and liberals, demonstrated a deft understanding of the political terrain. The Russians also paid Facebook to promote their posts in the feeds of American Facebook users, helping them test what content would circulate most widely, and among which audiences.

“This is cultural hacking,” said Jonathan Albright, research director at Columbia University’s Tow Center for Digital Journalism. “They are using systems that were already set up by these platforms to increase engagement. They’re feeding outrage — and it’s easy to do, because outrage and emotion is how people share.”
All of the pages were shut down by Facebook in recent weeks, as the company conducts an internal review of Russian penetration of its social network. But content and engagement metrics for hundreds of posts were captured by CrowdTangle, a common social analytics tool, and gathered by Mr. Albright.

Videos made by an American YouTube channel called CleanTV.com were reposted by a Russia-linked Facebook page called Secured Borders.
One Russian Facebook page, the United Muslims of America, frequently posted content highlighting discrimination against Muslims. In June 2016, it posted a video originally made by Waqas Shah, 23, an online video creator from Staten Island. In the video, Mr. Shah dressed in a thobe, a traditional ankle-length gown worn by Arab men, walked through New York’s Union Square, where he is shoved and harassed by another actor pretending to be a bully to see how bystanders react.
The video ends with Mr. Shah pointing out New York’s hypocrisy: The city claims to be a “melting pot,” but no one intervened while he was getting harassed. Mr. Shah’s original video, posted on YouTube in June 2016, was a viral hit that attracted more than three million views. A week after he posted it, United Muslims of America copied the video to its group page without the original YouTube link, a process known as ripping. There, Mr. Shah’s video become the Russian page’s most popular post, earning more than 150,000 interactions.
Mr. Shah said when he noticed the ripped video, he wrote to the administrator of the United Muslims account, asking them to add the link to his original YouTube video. His main concern, Mr. Shah said, was that the page was stealing his views. Told that his video had been used by Russian accounts to sow division in the United States, Mr. Shah said there wasn’t anything he could do about it.
“There are always going to be people who manipulate things to their agenda,” he said.
When Being Patriotic posted a brief message last year rallying Americans against proposals to expand refugee settlements in the United States, it was liked, shared or otherwise engaged with by more than 750,000 Facebook users. Eventually, it came across the feed of Len Swanson, 64, a Republican activist from Houston and an avid Trump supporter.
Mr. Swanson, who frequently posts long commentaries on LinkedIn and Facebook, then used the message and photo to open one of his own posts, attacking Hillary Clinton and the Democrats. The message Mr. Swanson borrowed also appears on a conservative meme website, with a photo that at least one newspaper has credited to the United States Navy.
“I usually publish an article several times a week, to keep driving the narrative,” Mr. Swanson said in an interview. He was not bothered, he said, by becoming an unwitting cog in the Russian propaganda machine. “You know we do the same damn thing over there,” Mr. Swanson said. “What do you think — we’re saints?”
In early 2016, Being Patriotic copied and pasted a story from the conspiracy site InfoWars, saying that federal employees had taken “land from private property owners at pennies on the dollar.” The Russian page added some original text: “The nation can’t trust the federal government anymore. What a disgrace!”

A Russia-linked Facebook page, Being Patriotic, posted a version of a message rallying Americans against proposals to expand refugee settlements in the United States. The message was reposted by American Facebook users.
This past March, another of the Russian pages, Secured Borders, reposted a video that it attributed to Conservative Tribune, part of the conservative and pro-Trump sites run by Patrick Brown. The video, which falsely claims that Michigan allows Muslim immigrants to collect welfare checks and other benefits for four wives, originated on a YouTube channel called CleanTV. The Facebook post has been removed, but a version remains up on the meme site Me.Me.
Mr. Brown did not respond to an email seeking comment. But Gerald McGlothlin, the president of CleanTV — and a contributor to other sites run by Mr. Brown — confirmed in an email that his company had created the original YouTube video.
The Blacktivist Facebook page appears to have specialized in passionate denunciations of the criminal justice system and viral videos of police violence, many of them gathered from Facebook and YouTube. In May, Blacktivist also posted a message drawn from news stories about the death of Jayson Negron, a teenager in Bridgeport, Conn., during a confrontation with police. Such posts soon found an authentic audience: The Negron post was reposted by a verified Facebook account belonging to Black Lives Matter Chicago, according to a cached copy.
As lawmakers debate tighter regulation for companies like Facebook, the trail of Russian digital bread crumbs underscores how difficult it will be to purge social media networks of foreign influence, or even to hamper the covert propaganda campaigns carried out on social platforms by Russia, China and other countries.
Copying other people’s content without proper attribution can be a violation of the social networks’ rules. But the content itself — the videos, posts and Instagram memes borrowed and shared on the Russian pages — are not explicitly violent or discriminatory, so they do not violate the rules of those services. Instead, they are precisely the type of engaging content these platforms are hungry for.
The Russian campaign also appears to have been tailored to exploit the companies’ own strategies for keeping users engaged. Facebook, for example, pushed people to interact more in Groups like the ones set up by the Russians, where users can “share their common interests and express their opinion” around a common cause. LinkedIn, the professional social network owned by Microsoft, is geared toward encouraging users like Mr. Swanson to create articles and other content.
“The strategies are no mystery,” said Michael Strangelove, a lecturer on internet culture at the University of Ottawa. “Foreign powers are playing within the rules of the game that we wrote.”

A spokesman for Facebook declined to comment. LinkedIn said Mr. Swanson’s post did not violate the site’s terms of service.
“The challenges posed by the dissemination of fake news and other harmful content through technology platforms are serious,” said Nicole Leverich, a spokeswoman for LinkedIn. “We actively address suspected violations of LinkedIn’s terms of service such as harassment, fake profiles, and misinformation on our platform.”
The Russians appear to have insinuated themselves across American social media platforms and used the same promotional tools that people employ to share cat videos, airline complaints and personal rants. Many of the posts on Being Patriotic also match pre-made, shareable graphics on sites like ConservativeMemes.com, nestled alongside other conservative content made for sharing on social media.
Boosted by Russian accounts, the material was quickly picked up by other American users of Facebook, spreading the posts to an even bigger audience. The Russian presence appeared to be layered throughout different platforms: Some of the Facebook accounts, including Being Patriotic, had linked accounts on Instagram and Twitter, according to deleted content captured in Google’s cache.
John W. Kelly, the founder of Graphika, a commercial analytics company in New York, said the Russians appeared to have a consistent strategy across different platforms. Graphika has tracked thousands of social media accounts whose content closely tracks Russian information operations, promoting articles and videos about WikiLeaks dumps of stolen emails and “false flag” conspiracies about Syrian chemical weapons.
The Russian accounts intermingle with real groups of Facebook or Twitter users — from white nationalists to Bernie Sanders supporters — and seek to manipulate and radicalize them, Mr. Kelly said.
The Russian-influenced networks frequently promote obscure conservative YouTube channels such as the Next News Network and the Trump Breaking News Network, driving up their views and advertising revenue. A video posted in February by a conservative internet radio host, who claimed that 30 politicians were about to be arrested in connection with the “Pizzagate” hoax, racked up more than 300,000 views on YouTube. Another YouTube video, claiming that Michelle Obama had 214 personal assistants and had purchased four yachts with taxpayer money, had close to a million views.
Rather than construct fake grass-roots support behind their ideas — the public relations strategy known as “Astroturfing” — the Russians sought to cultivate and influence real political movements, Mr. Kelly said.
“It isn’t Astroturfing — they’re throwing seeds and fertilizer onto social media,” said Mr. Kelly. “You want to grow it, and infiltrate it so you can shape it a little bit.”

The Devastation in Puerto Rico, as Seen From Above

Last week, Hurricane Maria made landfall in Puerto Rico with winds of 155 miles an hour, leaving the United States commonwealth on the brink of a humanitarian crisis. The storm left 80 percent of crop value destroyed, 60 percent of the island without water and almost the entire island without power, as seen in the nighttime satellite images below.

Cataño
Juana Matos, a neighborhood in Cataño, near the capital city of San Juan, suffered severe flooding as a storm surge from nearby San Juan Bay dumped water into coastal communities. Eighty percent of the homes in the Juana Matos neighborhood were destroyed, said Cataño’s mayor, José Rosario.

Mexico City Was Built on an Ancient Lake Bed. That Makes Earthquakes Much Worse.

The earthquake that on Tuesday killed at least 135 people in Mexico City and toppled dozens of buildings there was all the more destructive because of the city’s unusual position atop an ancient lake bed.
The animation above, based on a model by Víctor Cruz-Atienza, a professor of geophysics at the National University of Mexico, shows how the shock waves of a hypothetical earthquake near Mexico City would spread. Darker red areas indicate the strongest ground movement.
The shaking in this simulation is strongest in the low parts of the Valley of Mexico, which cradles the city, and it weakens when it meets the surrounding hills. That’s no coincidence. The darker red areas showing the strongest shock waves trace the shape of an ancient lake.

The Spanish built modern Mexico City over the ruins of the Aztec capital of Tenochtitlan, which they conquered in 1521. The Aztec city was on an island in Lake Texcoco, but the Spanish drained the surrounding lake over centuries and expanded Mexico City onto the new land.
Today, much of the city stands on layers of sand and clay — up to 100 yards deep — that used to be under the lake. These soft, water-laden sediments make the city uniquely vulnerable to earthquakes and other problems.

During an earthquake, the looser sediments near the surface cause shockwaves to slow down from about one and a half miles per second to about 150 feet per second as they enter the valley. The slower waves grow in amplitude, similar to a tsunami approaching a coastline, and cause more violent shaking.
Worse still, the denser, deeper material below the looser sediments causes waves to linger in the valley, making the amplified shaking last longer.
The map below, based on seismological readings taken at the National University of Mexico, shows how violently the ground shook in Mexico City during Tuesday’s earthquake. Like the simulation map, the redder the area, the more violently the ground shook.

These actual readings confirm what the simulation shows: Tuesday’s earthquake grew worse in the city as its waves moved through the ancient lake bed below.
Mexico City is already a hot spot for earthquakes because vast chunks of the earth’s crust, called tectonic plates, are slowly smashing into one another nearby. Mexico rests on the North American Plate, and the Cocos Plate slides underneath it along the country’s southwestern coast.

TUESDAY’S EPICENTER
COCOS PLATE
The collision as one plate plunges below the other, a movement called subduction, releases huge amounts of energy, making earthquakes a common occurrence in Mexico. Unlike Tuesday’s, many of these earthquakes are small.
The unique geology of Mexico City’s basin can amplify earthquake waves to be a hundred times stronger than they would be otherwise, a phenomenon that Dr. Cruz-Atienza said is not matched anywhere else in the world.
Partly because of this amplification, earthquakes that happen relatively far away from Mexico City can still cause significant damage. A devastating earthquake in 1985 that killed as many as 10,000 people originated over 200 miles away, near the Pacific coast of Mexico.
The epicenter of Tuesday's quake was closer, around 50 miles away, but the map below shows that it shook Mexico City more violently than other areas that were a similar distance from the epicenter.

The 1985 earthquake prompted improvements to building codes that are thought to have lessened the damage on Tuesday. But earthquakes will always pose a unique threat to Mexico City, because of the geologic implications of the ancient lake bed that lies beneath it.

Protest in Catalonia Adds to Pressure Before Independence Vote

BARCELONA, Spain — Hundreds of thousands of Catalans took over the center of Barcelona on Monday to mark their national day and raise the pressure on the Spanish government in Madrid before an independence referendum planned for Oct. 1.
The referendum has been declared illegal by Prime Minister Mariano Rajoy and suspended by the Spanish judiciary as a violation of Spain’s constitution. But separatist leaders in the Catalan regional government have vowed to go ahead with it, even if they risk prosecution for civil disobedience.

Since 2012, the Diada, or Catalan national day, has been turned into the annual show of force of independence-minded Catalans.
On Monday, the protesters filled two streets of Barcelona to form a “plus” sign, representing citizens joining forces. Some demonstrators said the cross symbolized the mark they will put on their ballots in favor of independence, assuming the referendum goes ahead.
The national day marks a historic defeat for Catalans, the 1714 capture of Barcelona by the troops of Philip V of Spain. “Philip V repressed Catalonia, and three centuries later here we are, getting denied the right to vote in the Spain of Philip VI,” said Oriol Cabré, a retired industrial engineer, referring to the current king.

Many demonstrators insisted that they would also step up their protests if the result of the vote did not then become binding — as their separatist leaders have promised it would be.

“Civil disobedience is sadly sometimes the only way,” said Manel Angurem, an international trade consultant who drove for about an hour with his wife and three children to Barcelona to attend the demonstration. “If it weren’t for civil disobedience in the United States, black people wouldn’t have managed to get a seat on the same bus as white people.”
Still, as in previous years, Monday’s protest was a festive and peaceful occasion, with some participants even forming the traditional Catalan castells, or human towers.

Catalans feel strongly about their distinct language, history and culture. But such feelings have become entwined in recent years with other issues, including how much tax revenue Catalonia should redistribute to poorer parts of Spain.
In addition to history, many of the participants cited pocketbook issues in wanting independence, after a financial crisis that helped fuel separatism in Catalonia.
“If we look after our own wealth rather than hand it over to Madrid, I’m sure independence will also bring us better economic conditions,” said Laura Solsona, who has a beauty salon in the town of Sabadell and had painted “Yes” on her forehead and a Catalan flag on her cheek.
Carles Puigdemont, the leader of Catalonia, assured the region’s voters that the independence referendum would take place, despite efforts by the Madrid government and Spanish courts to block it.
Catalan citizens “will vote, as they have always done in complete normality,” Mr. Puigdemont said. A referendum, he argued, would not escalate the secessionist conflict because “the ballot boxes don’t divide, they unite.”

The demonstrators held a minute’s silence in honor of the victims of the terrorist attacks last month in Catalonia that killed 16 people, most of them mowed down by a van driver on Barcelona’s most famous promenade. Few in the crowds on Monday seemed concerned about security.
“We’ve always shown respect, and we now hope that we can convince others to respect our right to vote and become another normal European state,” said Jesús Ribera, a trade union official, who had a sticker on his sleeve showing Catalonia as a future member state of the European Union.
“I can assure you that all the people here today will be standing in front of the polling stations on Oct. 1, even if they are kept closed and Madrid also manages to seize the ballot papers and boxes.”

As the political clock ticks toward the Oct. 1 deadline for the referendum, the tension between Madrid and Barcelona is rising. Prime Minister Rajoy is even weighing whether to take emergency measures to stop the vote, a step many fear would deepen the standoff.
Even the crowd estimates were disputed on Monday. Local police put the number at about one million, while representatives from the central government in Barcelona estimated it at between 300,000 and 350,000.
