The U.S. has formally announced the removal of NATO ally Turkey from the F-35 fighter jet program. The move came after Turkey purchased a Russian S-400 air defense system over vocal objections from Washington.
The big picture: Wednesday's announcement is about military hardware. But it’s also a manifestation of the widening divide between Turkey, the U.S. and NATO. While this breaking point long loomed on the horizon, both U.S. and Turkish officials hoped it could be avoided.
