Late on Monday evening, the Secretary of Commerce, Wilbur Ross, started making calls to European allies. A few hours earlier, they had got word from sources inside the Trump Administration that the President was poised to impose costly steel and aluminum tariffs by the midnight deadline. No one knew for sure (“The decision lies with the President,” German Chancellor Angela Merkel had said on Friday, standing next to Trump, after flying to Washington to lobby him personally), but it seemed like there could be a trade war between the United States and its closest partners within hours. Then Ross called the British Trade Minister, Liam Fox, with a reprieve: Trump had finally decided that there would be another month-long extension. The word came less than two hours before the White House publicly released the news. It was already approaching midnight in Europe. L’état, c’est Trump.

Little more than fifteen months into his Presidency, the attention-seeking President has the rest of the world right where he wants it: hanging on his every word, clamoring for personal meetings, beating its way to the Oval Office. He is the indispensable man. Soon he will meet Kim Jong Un, of North Korea, in an unprecedented nuclear summit. Next week, in advance of a May 12th deadline, he may single-handedly decide whether to blow up the Iran nuclear deal negotiated by the United States with the world’s five other major powers. The smart betting is that he will, but he may not. Nobody knows, and that’s the point: all roads now lead through Trump.

Indeed, Trump has set up the next month as an extraordinary display of high-stakes summitry and deadline brinkmanship, with himself right in the middle of it all. One way or another, we are likely to learn much more about his approach to the world in the coming weeks: Will he finally release his long-promised plan to bring Middle East peace to coincide with the May 14th opening of the new U.S. Embassy in Jerusalem, which he ordered moved from Tel Aviv and is seen as an affront by millions of Palestinians who consider Jerusalem their capital? Will he personally show up, as he recently hinted he might? Will he successfully rewrite the NAFTA pact with Canada and Mexico, or carry out his threat to withdraw from it as the latest round of negotiations comes to an end? What about actually pulling out of the Iran deal and the next deadline for steel and aluminum tariffs, now set for June 1st? Or, for that matter, the North Korea summit he agreed to impulsively, despite cautioning by his advisers; will he really go through with it in late May or early June?

With almost every decision, Trump risks alienating close allies of the United States in Asia, North America, and Europe, who are already feeling beleaguered by a President who treats them more like followers than partners. Twice in recent days, senior European officials told me variations on the following: Trump’s pledge of a foreign policy based on “America First” really may turn out to mean America Alone.

There is one nation conspicuously missing from Trump’s long list of upcoming deadlines and deals, but it has proved to be the most divisive one of all: Russia. Amid the metastasizing investigations of his campaign and business ties to Russia, Trump talks and tweets about the country more than ever these days, denying any knowledge of Russia’s 2016 election meddling on his behalf while leaving his true intentions opaque. He brags of being tougher than any other President toward Vladimir Putin one minute, then laments the lack of good relations the next.

On Monday, Putin, already Russia’s longest-serving leader since Joseph Stalin, will be inaugurated for a new six-year term. In March, Trump defied his own advisers by congratulating Putin during a post-election phone call, then surprised them again by inviting Putin to Washington for a summit meeting. It seems implausible and politically insane to imagine that Trump would even consider a chummy one-on-one with Putin now, especially when the risks to Trump from the investigation by the special counsel, Robert Mueller, into Trump’s Russia ties appear so significant. And yet the invitation, I’m told, was real, and reflects the President’s strongly expressed personal preference.

Will Trump follow through with it—and add yet another high-drama plotline to the already oversubscribed Trump show? I asked an array of current and former U.S. and European officials about it over the past few weeks, and the answers, as always when it comes to the mystery of Trump and Russia, are surprising, contradictory, and frustratingly incomplete.

When Trump had his phone call with Putin on March 20th, it was just days after Putin cleared seventy-six per cent of the vote in a Presidential election that Western election observers said failed to offer voters a real choice. Most subsequent reports about the call focussed on the sensational revelation, in the Washington Post, that the President had disregarded the “DO NOT CONGRATULATE” talking point that his staff had prepared for him, especially once Trump fired the national-security adviser, H. R. McMaster, the day after the embarrassing leak. Trump’s invitation to Putin was another surprise twist that the White House did not reveal in its readout of the call. Instead, in what appeared to be an effort to embarrass the American President, Trump’s friendly overture to Putin was announced days later by the Kremlin, after the U.S. joined a host of European allies in expelling dozens of Russian diplomats in response to a deadly nerve-agent attack on British soil. Days after that, the Trump Administration imposed a tough new round of sanctions on leading Russian oligarchs closely tied to Putin. Amid the escalating tensions, a coveted White House invitation for Putin seemed wildly improbable, but the White House confirmed the Kremlin overture.

Behind the scenes, there was much confusion among Trump’s aides regarding the Putin invitation, which once again called into question whether the President supported his own Administration’s increasingly hawkish policies on Russia. One American national-security expert who spoke with them told me that the U.S. Ambassador in Moscow, the former Utah governor Jon Huntsman, and a senior Kremlin foreign-policy adviser were surprised by Trump’s invitation. They both expected the main focus of the Presidential call to be Trump’s North Korea negotiations and how Russia, traditionally close to the isolated regime, might help. Right after the call, a senior European diplomat later told me, a Russian counterpart briefed on the discussion recounted to him that Trump and Putin had spoken for forty-one minutes, in a friendly and even joking tone, “and, at the end, there was the invitation to come to Washington.”

The European diplomat was shocked, not only by the invite, which at the time had not yet become public, but also because it occurred as Britain was organizing the mass expulsion of Russian diplomats by the U.K., U.S., and various European countries in response to the poisoning attack in Britain. Once again, when it came to a tough measure against Russia, Trump was proving to be an obstacle, expressing concerns that America not be pushed to do more than Europeans in response to what Trump viewed as a European problem. Over the weekend before the expulsions were announced, the European diplomat received four phone calls from a senior State Department official calling for his nation to expel more Russians. “I understood that they were worried that, if we don’t expel a lot of people, Trump will say, ‘Why are we?,’ ” the European diplomat recalled. In Britain, two senior officials later told me, convincing Trump to approve the expulsions involved enlisting support from France and Germany first, then a phone call from Prime Minister Theresa May explaining that the individual European countries’ expulsions, taken together, would be comparable to the number of expulsions by the U.S. that Trump had signed off on. The President then exploded when the American tally of sixty expelled diplomats was announced and those of individual countries such as France and Germany were much lower, the Washington Post later reported.
