US President Donald Trump said on Tuesday it is 'not fair' to either Turkey or the United States that Washington cannot sell Ankara billions of dollars worth of F-35 fighter jets after it bought a Russian air defense system. Turkey started taking delivery of Russia's S-400 air defense system last week in defiance of US warnings that doing so would mean the Pentagon would kick it out of the F-35 stealth fighter program and that it could be subject to sanctions. Washington's concern is that deploying the S-400 with the F-35 would allow Russia to gain too much inside information of the stealth system. Buying military equipment from Russia also leaves the NATO member liable to US sanctions retribution under a 2017 law known as the Countering America's Adversaries Through Sanctions Act, or CAATSA. 'It's a very tough situation that they're in, and it's a very tough situation that we've been placed in in the United States ... we'll see what happens. But it's not really fair,' Trump told reporters at a Cabinet meeting at the White House.
