Shafaq News / The final version of the must-pass annual defense policy bill unveiled Thursday mandates the U.S. president sanction Turkey for its acquisition of the S-400 air missile defense system.

Though President Donald Trump has held off sanctioning Turkey for the purchase under the 2017 Countering America’s Adversaries Through Sanctions Act, or CAATSA, the defense bill would order that five or more sanctions under CAATSA be imposed within 30 days.

The duty would fall to the Trump administration unless the bill is signed after next week. Otherwise it would fall to President-elect Joe Biden, who is due to be inaugurated Jan. 20.

NATO says the S-400s pose a threat to the military alliance and particularly endanger the technical secrets of the F-35 aircraft.
