Three days ago they had the power to the base cut off and a 'no fly' zone was created over the base. It has exactly one runway that would only take a few well placed bombs to put it out of commission. Yesterday they were still on 'internal power' (aka diesel generators).

Now, I'm sure the US would do everything they could to avoid those weapons falling the wrong hands but I think you're being a bit over-confident about the situation there, which even now is far from stable and the US/Turkey relationships are right now at a historic low.
