NATO potentially does. Look, I take your point -- especially since the main uses of western military force have been extra-extra-extra territorial since the disappearance of the main enemy (I boggle: it's amazing that countries can wage protracted wars on completely separate continents these days) -- but the realpolitik governing international relations privileges "national interests" almost to the degree that it privileges sovereignty. So when I say it's too late to respond by the time the enemy is crossing your borders, you may as well substitute "by the time the enemy is threatening your national interests," especially since, for the USA, these seem to include the defence of its allies. A major part, not forgetting the nuclear deterrent, of the national defence of many countries has been farmed out to the USA. Not just because they rely directly on US force, but because they buy a ton of weapons which it develops.
Well, maybe the national interest point is a little hyperbolic: the dissection of Ukraine is defended by various people because of the interests of Russian coethnics, and so on, but that doesn't make it correct. However, it is certainly interest and not principle which takes precedence at the negotiating table, and I would say that often hard power is what allows soft power to be actually used.
EDIT: I guess I was being dumb, European powers were totally waging long-ass wars throughout the colonial period. But still.
