Turkey to Look for Alternatives if US Doesn't Deliver F-35s by Associated Press ANKARA -- Turkey's foreign minister says his country could look "elsewhere" if the U.S. doesn't deliver F-35 fighter jets. Mevlut Cavusoglu also said in an interview with private NTV television Tuesday that Turkey could consider acquiring more Russian-made S-400s or other systems to meet urgent needs if it can't purchase U.S. Patriot systems. Turkey's moves to buy the Russian S-400 technology have heightened tensions with Washington. U.S. Vice President Mike Pence warned that Turkey was risking its NATO membership and its participation in the F-35 program. Cavusoglu said: "If F-35s are not delivered, I would be placed in a position to buy the planes I need elsewhere." He added that a new U.S. offer to sell Patriots was "more rational" than a previous offer, but still didn't meet Turkey's expectations.
