This is important. If Iraq is now under full Iranian control, they have a clear path to Israel for their jets, and also for ground troops and tanks, through Iraq, through Syria, then into Israel via the Golan Heights. Not good news.
Perhaps Israel should consider the EMP method.
Iraq has no way of knowing what is in aircraft overflying them.
Iraq has no air defense - anybody can fly what they want over Iraq.
That does not mean that Iran controls the ground...
