Since the genocide of palestinians does not affect their countries much, it is an easy issue to use, to flag themselves as being on the good side. That makes pushing propaganda easier, since they have at least one good point, so left-leaning people will start with considering them more likely allies than not. Also blaming someone here for supporting genocide is an easy way, to get people enraged, so they use it also as a derailment tactic.
