Erdogan is visiting Putin in Moscow on his first overseas visit after the attempted coup. That he has not visited the EU in Brussels, or the US, or any leading NATO ally should be a bit of a worry for the West.
Both men have said that they want to reset relations, starting with a 'clean slate', in order to go forward. That could mean many things. They are both despots wanting absolute power. Neither is too concerned about human rights, nor are they big fans of democracy. They share a border in the Black Sea and Turkey controls the Bosporus - the gateway to the Med and beyond.
If Turkey quits NATO and makes a pact with Russia they would make a formidable force. They each have large, well trained and well equipped armed forces and could cut the West off from the Middle East.
One to watch, as they say.
