1. Syria - Its a really good thing the Syrians are being backed up in the air by Russians because, if they didnt, the Syrian Civil War would last a lot longer than it already has. Almost every other power present in the region violates Syrian sovereignty on a near-daily basis. Israel, Turkey, and even Denmark have entered Syrian airspace, with Israel and Turkey both scoring air-to-air kills against Syrian Sukhoi fighters old enough to have fought against the U.S. in Vietnam.
