Nothing to do with Syria - a recent - last week - story. Try again.
The point is, Russia just made an arms deal with one of our adversaries next to Iraq. Syria is under US sanctions, but Russia did this deal anyway. So Russia, IMO, is working to undermine our interests in the area, and is trading with a country that is engaged in activities, namely supporting the terrorists in Iraq, that are killing Americans.
One would think that Russia, given their Chechen problem, would be disinclined to trade with a country that is sponsoring terrorism.
