Biden heads to Europe this week. Some Europeans are wary.

“The hopeful, optimistic view is that Biden is kicking off a new relationship, showing faith in Brussels and NATO, saying the right words and kicking off the key strategic process” of updating the transatlantic alliance for the 21st century, said Jana Puglierin, Berlin director of the European Council on Foreign Relations, to the New York Times. “But Biden also wants to see bang for the buck, and we need to show tangible results. This is not unconditional love, but friends with benefits.”
