Quite true but remember.

The idea of being in command of the high ground on both sides of the Straits of Mamaris was the reason for the Gallipoli campaign in WW1 - it would have been equally attractive following the establishment of the Iron Curtain.
While this is true it could as well have served as the geographic boundary between NATO and CENTO. That of course could have presented a fault line in the US containment plan and was resolved with Turkey being a member of both organisations.
