They have been in NATO since 1952.
I don’t know the early history of their membership.
Turkey was always guilty of extreme abuse of minorities. I’m not sure it was well understood outside Turkey and it was never admitted.
I have no answer for your question.
I was aware of their admission, however the whole premise of islam is antithetical to western civilization.
Was this the beginning of recent formalized lie that islam is a “religion” and not a political movement masquerading as a religion.
Does the Hells Angels have a “religion” stature yet???
During the Cold War Turkey was a reliable ally against the USSR because they were anti-Russian...the old "the enemy of my enemy is my friend" scenario. They sent troops to Korea during the Korean War...but they also took advantage of our need for their membership in NATO to invade Cyprus in 1974 and occupy 40% of the island.
