They should just fly a transport plane over Syria and kick his azz off the end with a parachute over Raqaa and let ISIS deal with him.
Then send ISIS a message through back channels detailing the he killed 3 Muslims, including 2 Muslim women of childbearing age. That would set that fertility-death cult on edge.
I’d be fine if he got the ISIS beheading treatment.
Seems like this idiot was a time-bomb waiting to go off based on his online postings.
