The point of that comment is that Liberals support whatever war the U.S. currently wages while at the same time pretending to be anti-war by condemning the “past wars” (the US still occupies a lot of the places they went to war with) because this time it’ll be different!
I fail to see how arming neo-Nazis and putting in Ukraine will play out any differently than arming religious fundamentalists did in the Middle East, every time I ask this I either get called a Russian troll or genocide apologist.
