many of these states and their governments are openly hostile to communist elements, but a communist party actively opposing their government would risk destabilising it and then playing themselves directly into the hands of the imperialist states. an indefinite “united front” would be desirable, especially in countries like iran, but it seems all leftist organisations in these states have either decided to fully support the government in everything, becoming controlled opposition (KPRF in Russia) or western puppets like (MEK) or whatever the fuck the “leftist opposition” in russia, belarus is.
I don’t really think that’d be effective. The CIA has translators and can recruit native speakers and a lot of historic anti-colonialist organizers were educated in the west and spoke good English (or other colonizer languages) so you’re alienating a lot of potentially good allies with that policy.
