For 75 years, NATO has anchored peace in Europe—powered by American might. But today, that foundation is shaking.

In this episode of The Delve Europe, host Chalin asks a question with existential stakes: Can Europe defend itself if the United States steps back? And what happens to the alliance if Donald Trump—or a broader shift in U.S. strategy—pulls the plug?

We hear from Justin Logan of the Cato Institute, who explains why U.S. presidents have long been frustrated with European defense spending—and why Trump’s warnings shouldn’t have shocked anyone. Then, we head to Paris to speak with Gesine Weber of the German Marshall Fund, who outlines what Europe would need to do to build real autonomy—and why the continent may be forced to grow up fast.

This episode takes you from post-war promises to modern battlefield realities. The transatlantic alliance is at a crossroads. Will it hold—or fall apart under pressure?
