Then there is the jet that was shot down in Deir Ezzor area with a shoulder launched missile. Russians said early on that it was made in the USA. I think they concluded that it was shipped to that area by Turkey and was in hands of one of Turkey's Jihadi groups. I never heard if the person who actually used it was ever identified. I'm sure something that expensive would be heavily tracked.
Putin was an accountant for the KGB. He is methodical. Obviously he learned other traits there too.
I agree, this will not end well for Erdogan or Turkey.
The Deir Ezzor event involved a helicopter; any US weapons used could have come from almost anywhere.
Erdogan then over-extends agaisnt Kurds
Erdogan gets himself kicked out of NATO, so no NATO support against an attack by outsiders
Russia gets the Dardanelles.....
