I am confident that with some decent leadership the Iraqi army is capable of taking care of them.
They simply need to be told that they need the go towards ISIS and kill them. If they surrender, ISIS will crucify them. If they retreat, they will be shot. So, the best option is to just take out ISIS and everyone is happy.
“So, the best option is to just take out ISIS and everyone is happy.” — I really like to know who is/was behind Islamic State (IS). Many suspect more than one culprit, and don’t mean al-baghdadi alone. Looks like he is the knight in a chess game. Because yesterday was Muslim Brotherhood, AQ, & today IS & tomorrow other incarnations of aforementioned? I believe there will be.
