West Is in Danger of Losing Turkey, US Warns Jeff Seldin The United States is warning Turkey against taking any additional steps to operationalize its Russian-made S-400 air defense system, warning there will be consequences even if that risks pushing Ankara closer to an alliance with Moscow. Relations between Washington and Ankara, which have soured in recent years, hit a new low last week when Turkish President Recep Tayyip Erdogan confirmed his military had [1]tested the Russian-made system. The announcement sparked condemnation from U.S. defense officials. A key State Department official said Wednesday that the risk of new sanctions against Turkey was "very real." "Sanctions is very much something that is on the table," Assistant Secretary of State R. Clarke Cooper told reporters. Not compatible Not only is the S-400 not interoperable with U.S. platforms, Cooper said, but "it is not interoperable with NATO." "Operationalizing such an asset or system incurs further risk of sanctions and further risks of restrictions," he said. "What we have here is efforts to get [2]#Turkey to walk back from operationalizing the [3]#S400" per [4]@AsstSecPM "Put it away, decommission it. Just do not integrate it and make it operable" -- Jeff Seldin (@jseldin) [5]October 28, 2020 Turkey signed a deal to buy the S-400 air defense system from Russia in 2017. The first deliveries began in July 2019. Since then, the U.S. has suspended Turkey from participation in its F-35'¯stealth fighter jet program'¯and has repeatedly threatened sanctions against Ankara, though none have been levied. Cooper on Wednesday indicated U.S. patience with Ankara might be running out. "What Turkey squandered over the last year is an opportunity to reconcile and get back into a good space and a good path with the United States and NATO," he said. U.S. officials'¯warn Turkey's'¯use'¯of the'¯advanced Russian radar technology could compromise'¯NATO's'¯military systems'¯and'¯could be used to target NATO jets in Turkey, including'¯the'¯F-35.
