Two weeks have passed since the meeting between Donald Trump and Vladimir Putin, but there is still no public account of what the two leaders said—other than their own self-congratulatory remarks. But the recent actions of the U.S. and Russian presidents suggest they may have discussed the role and ambitions of the North Atlantic Treaty Organization, taking steps toward a rebalancing of power that should worry Europeans and Americans alike.
President Trump provided one clue in his statements about Montenegro, a tiny Eastern European country and the newest NATO member. During a July 18 conversation with Fox News’s Tucker Carlson, he suggested that “aggressive” Montenegrins might start a global conflict. To be fair, Mr. Trump didn’t raise the subject; it was Mr. Carlson who suggested that honoring NATO’s mutual-defense obligation might entangle the U.S. in a fight Americans would rather sit out. But once the subject was raised, Mr. Trump pounced—conjuring the specter of Montenegro dragging the U.S. into World War III.
Where did that come from? There’s no evidence that Mr. Trump had any earlier concern about Montenegro, or even that he knew where it was. Though Montenegro joined NATO shortly after he took office, Mr. Trump’s only direct interaction with the country on record came during a photo session at last year’s NATO summit, when he shoved aside Montenegrin President Dusko Markovic to get a spot in the front row.
There is plenty of evidence, however, that Russia is worried about Montenegro’s accession to NATO. The Kremlin promised unspecified retaliation against NATO in 2015 when the alliance first formally offered membership to Montenegro. Senior Russian officials claim that, in adding the Balkan country to the alliance, NATO members violated their promise not to expand the alliance eastward—an assurance they had given Russia during the presidency of George H.W. Bush.
