Erdogan Risks Sanctions With April Date for Activating Russian S-400s

Turkey will activate its Russian-made S-400 missile-defense systems in April, President Recep Tayyip Erdogan said, possibly setting his country on a collision course with its NATO allies.

“The S-400s are our property now. We’ve taken delivery of all of it. They will be made operational in April,” Erdogan said on his return to Istanbul from talks with Russian leader Vladimir Putin in Moscow, according to Turkish media.
