This threat is pure bullsh@t. Know any French or British who are willing to get themselves killed to “defend Turkish air space?” We don’t. They won’t even defend their own villages against the islamonazi invasion. Europe ( excepting a couple nations like Hungary perhaps) is a lost cause - sold out by rheir ruling elite (like in USA ) to the islamonazis.
The NATO tough guys in Brussels would have already acted but for having to pray five times a day.
