Yeah, the bottom line is that Americans aren't interested enough in the rest of the world to build a socialist movement around anti-war sentiment (and that goes double for the more complex idea of anti-imperialism). I don't see any scenario where there's a broad anti-war movement that later turns into socialism. It didn't happen during opposition to Iraq, Vietnam, WWI, the Spanish-American War, etc., etc., etc.
On the other hand, I can see a socialist movement focused on domestic policies gaining steam and that later turning into not only an anti-war movement, but an anti-imperial one. There's a well-beaten path from Medicare for All to "yeah, I'm a socialist" to "holy shit we need to tear down this imperial death machine."
