Europe is already deeply divided between populist nationalists — some of whom flirt with Vladimir Putin — and globalists who defend multilateral institutions and view Russia as an enemy.

What we're hearing: Ivo Daalder, the former U.S. Ambassador to NATO and coauthor of the upcoming book "The Empty Throne: America Abdicates its Global Leadership," tells me he worries Trump will side with the nationalist leaders and hand Putin a win this week.
