Re: The U.S. has threatened to expel Turkey from the F-35

Why don't the Russians fear, that the secrets of the S400 are falling in NATO's hand? Using Turkeys S400, NATO could thoroughly develop and train tactics and flight profiles to penetrate S400 protected airspace. Even using 4G aircraft, NATO would be able to find the weakest spot of the system. I am ...
