Because liberals supported the Vietnam war. And they never repented.
Could not argue that.
The reality here is that non-leftists are for Empire and always support Empire. While leftists do NOT always support Empire, especially when it is their own country doing Empire. Yeah, leftists, of which I take it you, UL are not, are not following lockstep behind the imperialism and ensuing war. We leftists, unlike gun nuts, neo-nazis, an assorted other big bad asses, question authority and wonder why war is their favorite answer to every uprising of oppressed peoples.
My suggestion is that you repent and declare your fealty to no-more-war. Like the leftists do.
