The problem seems to be Iran is taking over Syria. It certainly is complicated.
Turkey is also involved and not friendly to Russia. Private military
contractors might be useful as Iron Rod states.
Russia learned from our experiences in Iraq by deploying private military
contractors. Less problems when they die. Recently a US Air strike killed
dozens of these Russian military contractors. With ISIS gone are we going to
end up fighting the Russians and the Syrians? The Russians were invited in by
Assad. Who invited us in??
