ISTANBUL — As the Turkish government attempts to recalibrate relations with the new US administration under President Joe Biden, its acquisition of Russian-made S-400 missile defense systems remains a central point of contention between the longtime NATO allies.
Speaking in a press briefing Tuesday, Pentagon Press Secretary John F. Kirby urged Ankara to take action and remove the missiles from Turkish territory, reiterating a stance widely held by Washington officials that the S-400s pose a security threat to NATO defense systems in the country.
