Europe Has Found the Will to Spend. It Has Not Yet Found a Permanent Way to Finance It.
Europe has pledged to spend €800 billion on defense by 2030, and the political will to do so is real. NATO's new target is 3.5% of GDP by 2035, rising to 5%. For most member states, this means roughly doubling current defense budgets.
The financing architecture is temporary, unequal, and contested. The national escape clause—which provides the bulk of fiscal flexibility—expires in 2028. Five member states have debt above 100% of GDP and limited room to borrow. Defense competes with green transition, ageing, digital infrastructure, and rising debt service for every percentage point of fiscal space.
Europe has found emergency fiscal mechanisms, but it has not yet built a permanent financing architecture for the level of defense spending the security environment demands. That architecture—not the money itself—is the binding constraint.
