I wonder what the Turks would do if Russia fired a four or five thousand land-based missiles into Istanbul or Ankara?
Invoke Article 5 of the NATO treaty.
I would assume Turkey’s biggest leverage are the straights connecting Black Sea to Mediterranean.
Russia is likely waiting for a clear and egregious attack by the Turks so they cannot invoke Article 5 - or that’s what I would do - and then Russia will slam the Turkish mil to pieces, giving the Kurds the contiguous state along Turkey’s southern boarder.
I fear when Russia blows up like that, it will be nukes sent to Turkey and Saudi Arabia. Maybe the US, too.
