The only field where I'd favor more military spending is humanitarian interventions. But, apart from transport planes and a unified Euroforce (which are coming), what this would need most is not more spending and more weapons, but more training (to avoid civilian casualties, and to not rish long-term negative economic, social and political consequences with short-term force protection decisions) and much deeper policy pre-planning, and of course strong checks and balances to prevent the abuse of this power for other goals (economic, geopolitical, dominance). Possibly best done under a UN umbrella, the EU delegating power.

Only, by today, I am growing increasing doubts that this is realistically possible. That is, would politicians ever agree to something like this, or would be able to do sufficient policy pre-planning.
