If Iran is no different than the Muslims trying to overthrow Assad, why don’t you favor Russia selling them S-300’s? You’re situationally pro-Putin for arm sales.
NO ONE.... Not Russia or the US should ever have sold the Muslim Countries any weapons ever. But both nations are very guilty of this. The Russians had to face their own weapons in Afghanistan, we faced some of our own weapons in Iraq and if we ever have to do anything with S/A we will totally face our own weapons. Even Iran has US weapons (old but there). The Muslim Countries are not our or Russia’s friends but both Countries continue this stupid self defeating supply line to people we should have left to fight amongst themselves with swords.
