I say we deal with ISIS/Iraq through a policy of preemptive reprisal. The same with Afghanistan.
In addition to that, the intelligence and special communities should be running covert ops designed to kill any threat that comes up in Iraq/Afghanistan.
Finally, using the covert forces of other nations who are also enemies of Iraq/Isis and Afghanistan and whose interest might parallel our own at any given moment is a simple matter of clandestine coordination.
I can hope I am wrong.
Wishes and hopes won't change what is happening, and what will happen next.
The lunatics are now in charge of the asylum.
