Ah yes, our good friend and ally Turkey. Sometimes I wonder if they really should be our ally.
As far as I know there is no mechanism in place to remove a member of NATO. Even if there was, I'm not sure it would be a good idea to boot Turkey from the alliance. I bet Russia and Saudi Arabia would be eager to cosy up with them, not to mention how valuable a member they would be if NATO ever happens to be attacked by a major power.
I think the biggest advantage of kicking them out would be as a warning to other member nations. "Here is what happens if you turn autocratic." Looking at you Hungary and Poland.
So just make it impossible to reverse engineer..?
Are you worried about them selling the designs to non-allies?
