There is no need for this campaign to be led by the same nutcases.
Why will you not allow other nutcases an equal chance to fuck things up?
The only viable option is to launch a ground operation under the command of the United Nations, in Syria and Iraq against the ISIS. Countries such as Russia, the United States, China, India and Germany should provide soldiers for such an operation. The ISIS should be eradicated once and for all. And a sizable contingent of the UN peacekeepers should be maintained in both Iraq and Syria, to make sure that the remnants of the ISIS will never surface again.
There's really nothing wrong with stationing ground troops in areas that have some basic instability and more of such expected in the future. The UN "peacekeepers" have had some pretty sordid track records of course, and there are cases where they had guns.
But no bullets.
