The extremists have taken over Turkey. I would no longer consider THEM an ally, and that would be true if Sarah Palin was President!
They never were an ally, for awhile we had shared interests out of fear of the Soviets.
If I recall correctly they wouldn't allow U.S. troops to deploy through Turkey for the Iraq invasion when Bush was president, and wouldn't allow their bases to be used for air strikes. So I don't think they've been much of an ally for some time.
