What happens if NATO allies can’t trust that the United States will trade Boston for Berlin?
The answer is not to mimic the American model with tactical nukes scattered across the continent. If Paris and London were to extend deterrence, it would be because their national security is inextricably tied to Europe’s stability. Any adaptation must reflect this.

The Franco-German Brigade and the Revival of European Defense
One thing has been clear since Donald Trump's return to the White House: the very existence of the European unification project is threatened. Unless it develops a sovereign defense policy to counter the war in Ukraine and the weakening of American security guarantees, the European Union will continue to see its internal cohesion and external attractiveness wane.
