“According to Hans M. Kristensen, the director of the Nuclear Information Project at the Federation of American Scientists, underground vaults at Incirlik hold about fifty B-61 hydrogen bombs—more than twenty-five per cent of the nuclear weapons in the nato stockpile. The nuclear yield of the B-61 can be adjusted to suit a particular mission. The bomb that destroyed Hiroshima had an explosive force equivalent to about fifteen kilotons of TNT. In comparison, the “dial-a-yield” of the B-61 bombs at Incirlik can be adjusted from 0.3 kilotons to as many as a hundred and seventy kilotons.”

I guess obama and our national security guys were too busy playing Pokemon Go and this whole Turkey thing caught them by surprise. It would have been nice if someone might have said “Hey guys - Turkey doesn’t seem the most stable place to store half our stuff right now. Maybe we should move some of them?”
