The State Department calls on Turkey to return the S400 and not to use them.
“Our position on the S-400 system has not changed: Russian S-400s are incompatible with NATO equipment, threaten the security of NATO technology and are inconsistent with Turkey’s commitments as a NATO ally“, he says characteristically in his answer to a question from a Greek journalist, as relayed by SKY and adds: “This significant transaction (purchase) from Russia triggered CAATSA sanctions under US law. We urge Turkey not to maintain the system.
THE Turkey is an important NATO ally. However, the acquisition of the S-400s directly contradicts commitments made by all Allies at the 2016 NATO Summit in Warsaw to reduce dependence on Russian equipment.
We urge Turkey, and all US partners and allies, to avoid future purchases of Russian arms, including additional ones S-400, which provide Russia with revenue, access and influence. Any such transactions could be subject to CAATSA penalties separate and in addition to those already imposed.”
