Communists can also make bad calls. There are times where communist insurrection has no potential to do something other than enable a takeover of reactionaries even worse than the current ones, and the business of communists should in those cases probably be more oriented toward whatever course of action represents enduring progress in defeating reactionary factions without getting wiped out themselves. If an even more reactionary and vicious government gets installed, is that really going to help Iranian communism?

These periods of unrest are definitely good for agitating on their part, but that doesn’t mean defending the same people Mossad is promoting, and if some self-styled leftist is telling you that their lived experience is that following Mossad’s agenda is a good idea, you should probably not support them except in the lucky circumstance where the consequences of their actions “merely” result in them becoming refugees (who then might need material support to survive).
