"US officials have warned that if Ankara goes ahead with its plans to purchase the S-400 system, the United States could withhold the transfer of F-35 jets to Turkey. In addition, the US Congress passed legislation that would block the transfer of F-35 jets"

Is this some kind of joke?
It's obvious why Turkey want's S400s but why would they want F-35s. Everyone knows the F-35 is a useless heap of junk.
