pretty much. it is the same reason those parties largely went along with WW1. Ireland was the first, even before the Russians, and eventually ended up being the only other european revolution of that time to somewhat stick even if betrayed and leading to a civil war. I think much of that comes from the fact that the irish by and far didn't have the opportunity for comfort. You had the classic Irish elite who sold them out sure, but some concessions had to be made to them because their status as a colonized people made for a contradiction that could not even be temporarily resolved. You never got something close to that in Germany, while in Ireland people who otherwise would be SPD or tuned out of politics, engaged in revolutionary action and aligned with the nascent Soviet Union
