Why Turkey?
In a very similar situation to that Poland, locked between Communist East and Fascist West. If Turkey tried to help Germany invaded through the caucasus things could've gone differently since vast quantities of Soviet oil were in Baku. Turkey could also potentially work to get the lands they last when they were the Ottoman Empire, or perhaps create their own faction based. Could also align with the Allies to act as a buffer to their colonies and the suez.
