Sometimes a war is justified, and coming to the aid of an ally getting invaded is a damn good justification.
Especially if that ally is simply asking for more hardware and not asking for feet on the ground.
Edit: Fixed the link, it was broken for some reason though it worked earlier today. IDK this mirror should work though
You've got it the wrong way around. I'm talking about people that call themselves "anti-war" or "anti-imperialism" but hold positions opposed to that, specifically. The kinds of neoliberals you're talking about don't generally claim those positions to begin with, so I'm not talking about them. They aren't even offering lip service on being anti-imperialism, they're just pro-western interests and occasionally that lucks them into a somewhat correct position. There's more than one way to be a shitlib, you know.
