Possibly cooperation of Turkey with the "Islamic State" began when the USA was also promoting IS (ISIS / ISIL) as a way to overthrow the Assad government of Syria.
The current relationship of Turkey to the "Islamic State" is a significant question, IS being now in power about 100 miles (3-4 hour trip) away from Incirlik airbase, with no mountains to cross. IS is reportedly in power just outside Aleppo, Syria. Just look on a map as to how near IS is to that airbase, defended I think by only about 5000 airmen in Turkey. Incirlik airbase is the location of about 60 hydrogen thermonuclear bombs, I believe. Evidently Turkey lets IS send supplies through Turkey to Syria. Should the USA either remove its H Bombs from Turkey or send in a large army to defend them?
