It's all goes back to invading Iran, there is a plan in motion for last 25 years to occupy Iran, you think I'm wrong?
See they first invaded Afghanistan then Iraq then they tried to go straight to Iran but the missiles were delivered through Syria to Palestine and they started to attacking Israel with heavy fire power which made them to reconsider to invade Iran because then nothing would have be left from Israel.
Now they trying to block the access points for Hamas and other resistance groups, but Iran started to manufacture long range missiles which can be launched from there straight to Israel.
ISIS was established to weaken Iran's position with the hidden agenda to weaken Russia at the same time.
They now turned against them and bombing EU and soon US soil even without Iran or her allies have anything to do with it.
Can you tell me where did they get $2 trillion in their pockets according to the 2015 UN reports? a terrorist group having that amount of money is not by accident.
