World leaders wrapped up a significant NATO summit in Washington this week. President Joe Biden hosted this year's event as he faced questions over his ability to lead the country after his dismal performance in his debate with Trump. 

Those questions brought new attention to Trump’s ambivalence toward the alliance, and new questions about the U.S. role in NATO should Trump be returned to the White House.

“There's this huge cloud hanging over it and NATO member states are aware of it that a Trump presidency might mean quite a shaky time period for the alliance going forward,” says Brian Taylor, professor of political science and director of the Moynihan Institute of Global Affairs. 

“President Biden has decades of experience with respect to dealing with NATO member countries and understanding the alliance. And President Trump has a much more negative and hostile attitude towards the alliance. So in terms of what the November election means for foreign policy, there's a pretty sharp difference between the likely Democratic and likely Republican candidate in the coming election,” he says.
