You are correct on that - I don't know much about the Middle East particularly Syria and Turkey. All I know about Turkey is that it is a melting pot of different races but this I learned from a friend who works there. I don't have a good mind of history, a bit forgetful sometimes. But I believe that Russia will do something to retaliate, just my opinion. But I heard in the news this morning that US had confirmed that Turkey air force had warned the Russian plane more than 10 times, that's a justification of the shotdown.
Why would Russia retaliate when being the aggressive here? Russia violated Turkish Air Space and such a reaction is justified.
