Trump's 'dj vu' Eurotrip: Upcoming Putin, NATO summits raise concerns after G7 debacle

There's an old Russian saying that U.S. President Donald Trump might heed as he departs Tuesday for a week of high-level meetingsin Europe, including onewith a foreign foe. It goes: "Repetition is the mother of learning."

Those words may help him navigate a familiar scenario a potentially strained meeting withallies just ahead of a tte--tte with a major U.S. adversary.

"Dj vu is one way of thinking about it," said Alina Polyakova, an expert on Russian foreign policy at the D.C.-based Brookings Institution.

It was only last month that Trump travelled abroad to meet, theninsultone of his country's closest allies, Prime Minister Justin Trudeau, before he departed to laud a Western adversary, North Korean dictator Kim Jong-un.

NATO members "are trying to understand what this president might do, and watching how he's interacted with other authoritarians Kim being the most prominent recent example," Polyakova said.

"They're trying to take lessons from that."

But if it's solidaritythe alliance of29 North American and European powers is after,Trump seems comfortable playing the role of disrupter, lashing out at members over military spending while treatingRussian President Vladimir Putin amicably.

'Europe is almost powerless'

Trump will enter the talks in Brussels amid an already strained relationship with German Chancellor Angela Merkel.

Last week, the White House sent missives to several NATO leaders, includingTrudeau, admonishingthe U.S. allies for their defence spending shortfalls, though the spending guidelines are not formal rules, only targets.

Making things more awkward will be the steep tariffs the U.S. is imposing on imported steel and aluminum from the EU, Canada and Mexico.

In June, Trump departedthe G7 in Quebec, then rejected a joint communiqu, in order to meet with Kim in Singapore. Now, NATO members are reportedly concerned about whether the president will renege on U.S. commitments to the alliance before his one-on-one with Putin.

The Europeans won't like the sequencing, Polyakova said, especially if a routine diplomatic affair goes off the rails, asthe G7 did, leadingright into a "glowing meeting of Trump and Putin."

"It's like Europe is almost powerless as they have to sit by and watch as their fates are decided by two men," she said, the implication being that Russia is back at the table with superpower status.

Putin would likely request a lifting of sanctions, she said.

'Putin's wish list'

Trump reportedly hinted at the G7 that Crimea in Ukraine should belong to Russia, reasoning that most citizens there speak Russian. But legitimization of Russian annexation of Crimea would be a huge win for Putin, possibly incentivizing other land grabs, said Brian Klaas, author of The Despot's Apprentice: Donald Trump's Attack on Democracy.

"It's not just about Ukrainian territory, it's about a bedrock principle that has created international security and prosperity since World War Two, and that's the principle that you can't divide by force."

Alliance members worry that the U.S. would withdraw its forward presence in Baltic states such as Estonia, Latvia and Lithuania, leaving them vulnerable to a possible Russian military offensive.

If Trump was distracted during the G7 by his summit with Kim, his planned sit-down with Putin threatens to overshadow NATO discussions set to begin on Wednesday, said Klaas, a comparative-politics fellow at the London School of Economics.

"The Western world is held together by NATO and the European Union, and Trump is attacking them at the same time he's trying to make friends with Putin."

After all, he said, "NATO exists largely to deter Russian aggression."

A weakened NATO and a U.S. president who's seemingly reluctant to criticize the Kremlin "are literally what Putin's wish list has been for the last two decades."

Article 5'in question again'

How Trump can square his commitments to what the alliance stands for with a cozier relationship with the Kremlin will likely keep NATO members on edge. They will want reassurances from the Americans, Klaas said, and Trump campaigned in the 2016 election as a NATO skeptic.

It took Trump nearly half a year into his presidency for him to formally endorse NATO's Article 5principle of collective defence, in which an attack on one member is considered an attack on all allies.

"I think that's up in question again," Klaas said.

Polyakova'sworry, based on reports of satellite images showing ongoing nuclear activity in North Korea, is what kind of concessions Putin may be able to extract from Trump "without getting much in return, if anything at all."

Kim may have deceived this administration, she said, "but Putin has shown himself to be absolutely untrustworthy as a partner, potentially more so than Kim."

Experts expect Trump to continue pressing NATO allies towardmore burden-sharing, in line with a 2024 goal for members to contribute two per cent of their GDP on defence.

In 2014, only four partners were meeting those targets. Trump wants more. His lobbying may have succeeded in that regard: eight countries nowmeet the spending targets.

"That's already a positive move," said Elena Sokova, a nonproliferation expert at the Middlebury Institute of International Studies at Monterey, in California. "Because no matter how you slice and dice it, there's a need for countries to be stepping up their spending for allocations for the military budgets."

Despite the president's rhetoric, his administration has arguably reinvigorated NATO, hiking spending on European defence by approving $6.3 billion.

A more fortified NATO is bad news for Putin, though he's at least scored a win by securing a meeting with Trump.

The president, for his part, said he is "looking forward" to the meeting in Finland, though one of his tweets on Monday raised eyebrows about just how willing he'll be to take the Russian leader to task.

Following reports that Kim had not honoured what Trump termed a denuclearization "contract," Trump wrote that he remained confident the North Korean would stay true to his word, based on "our handshake."

That reminded Sokovaof Trump's rationale for doubtingthe Russians meddled in the 2016 U.S. election.Trump said hewas certainbecause Putin told him so.

"You could say that's the equivalent of a handshake," Sokova said.
