It is only western leftists, at least in my experience, who engage in this kind of moralistic peacocking over people who by now are all either dead or very old.

Like yeah the viet cong were justified in doing whatever they had to do to get the US out of their country, even if that meant shooting teenagers conscripted against their will. But it's only in the US and Europe that you see leftists kind of reveling in post-hoc revanchist violence.

I think its another symptom of there being no consructive, material political project for people to rally around, and a reaction to the fact that we live in easily the most jingoistic, propagandized society on thr planet.
