This is the way the world works. Wars are fought for acquisition. They won the war a long long time ago. It is theirs with no limitations or restrictions to do with as they will. Ataturk played nice as a gesture of peace to the world. The new guy not so much. But it is his to do as he wishes.
The only way to change it is to wage war to take it back. If not willing to do that then be a good loser and leave it alone rather than whine the new guy doesn’t play nice.
On the other hand, there is a very similar situation some few hundred miles south of Istanbul.....
