The Washington Post reports interesting developments from Syria. Russian air strikes are working, reducing the chances of a negotiated settlement. In other words, Putin is helping Assad win, albeit slowly.
The article doesn't say so but I am of the opinion that Russian air strikes are succeeding where ours failed because the Russians don't obsess over civilian casualties like we have. It is widely reported that a majority of U.S. air strikes return to base without dropping any ordinance (i.e., bombs, rockets, cannon shells). You can be certain the Russians do no such thing.
