Something I’ve noticed.
The one thing Israel NEVER bombs in Syria...ISIS or rebels”.
They only bomb Government forces or allies fighting the sunni rebels.
#1: Israel has extensive knowledge of ISIS activity in Syria and feeds it to those who are fighting it, be it USA, Coalition parties, Russia and even Syria itself. Not only is it not Israel’s job to directly fight ISIS, but the US coalition does not want it to, it will only inflame the issue
#2 Israel’s job is to fight IRAN which with its activity in Syria threatens Israel directly. Israel is 100% connected with the US Central Command and it is assumed that everything that happens is planned and agreed on.
Israel bombs pro-Iranian militias because Iran is the greatest threat for Israel. ISIS is more ruthless, but technologically impotent (=not a big threat for a competent military).
