Why crisis-driven defense spending may not persist

Would European governments sustain their new defense spending after the immediate crisis passed?

Many governments might reduce it once the immediate danger faded because they often expect domestic alternatives to win more votes than defense spending.

Political incentives can make crisis-driven defense spending temporary. Emergency appropriations are easier to justify while danger is visible and immediate. Once the adversary appears weaker, elected governments may redirect money toward policies they expect voters to reward more directly. Long-term military capacity therefore requires durable political commitment rather than a single crisis budget.
