U.S. should impose sanctions on Turkey over S-400 without any delay - Jerusalem Post

The United States should impose sanctions on Turkey over its purchase of Russian S-400 missile systems without any further delay, said columnist Diliman Abdulkader in The Jerusalem Post on Friday.

The two NATO allies have been in a row over the S-400 purchase for months, with Washington arguing that the Russian systems are both incompatible with and pose a security threat to NATO defence systems.

U.S. President Donald Trump halted the delivery of 100 F-35 stealth fighter jets ordered by Turkey, after Russia started transferring S-400 components to the country in July. The United States also suspended Turkey’s participation in the F-35 joint manufacturing programme.

Turkey risks further sanctions under the Countering America’s Adversaries Through Sanctions Act, or CAATSA, which aims to deter third parties from defence partnership with Russia. There is bipartisan support in the U.S. Congress to take further punitive measures against Turkey. 

"The correct decision is for Congress and the administration to take a unified stance and sanction Turkey based on existing law. Congress must convince the president of violations committed by Turkey to implement the bipartisan CAATSA bill," Abdulkader said.

Turkish President Recep Tayyip Erdoğan relies on his warm relationship with Trump for the cancellation or mitigation of measures against Turkey, Abdulkader said.

Currently, the United States appears to have postponed the planned CAATSA measures, until Turkey activates the S-400s.

"NATO allies now fully believe that Congress can be bypassed as long as they have a good relationship with the president," the columnist said.
