Turkey, after Ataturk’s reforms, was ready to leave the muslim world behind, or so the thinking went, and join the Western nations. That didn't work out so well either.
As for surveillance of Russian ELINT, Turkey was much like Pakistan, but easier to access, it was also the only place which could get good tropospheric internal communications (phone calls and Molnya data), data dumps from Soviet mil and deep space satellites, direct access to cosmonaut comms, and also (until they went over to all landline) the only place to intercept the Soviet launch telemetry from Baikonur.
The U2 intel was great, but the ELINT was priceless
But, more often than not, the Turkish military hindered collection whenever they saw an opportunity.
Today Turkey, with its move to hardline Islam, is becoming more chaotic and dysfunctional internally, thus fast approaching irrelevance as a NATO member.
I was in the middle east in the 1956-58 period, and nothing much seems to have changed. In the fall of 1957 there was a border dispute between Syria and Turkey that led to a near war. The Soviets announced their support for Syria, and , of course, we responded by sending a team up from Wheelus AFB in Libya to estabish a radar operation at Incerlic, 56 miles from the border. I was a part of that team. A standoff ensued, thankfully, and within a couple of months it was over. Just recently there was a border dispute between Syria and Turkey, and still the Jews and Arabs still hate each other, there are coups and plenty of brutal killings, and that ever burning sand. It is never changing, or so it seems to me.
