Yes, I think it does. Not saying people consciously plan it like that, it's just the one option left once you discard everything that capital might not like. For capitalists, war promise a stabilizing effect in the face of deep crisis. But leftists in the imperial core can turn the effects of war against the ruling class by waging struggles over who should pay for the blowback. Strikes against inflation, social cuts and against war funding in general. The war will end, when it no longer seems to promise profit opportunities.
