Specifically, can this be spun up and used by Iran to justify attacks on fellow Muslim countries, like Iraq, Kuwait, Saudi Arabia, maybe rump states to close the Gulf, and succees in giving them impugnity for same?
Or do they need more to justify that kind of offensive?
Nah.
Syria's going a little wobbly on them, and they're trying to get them back in line.
