Obama is showing himself once again to be a confused, cowardly fool.
Even though Russia's agenda is somewhat different as that of the US, they both share the same objective of destroying the Islamic State, therefore this petulant policy makes no sense as all the American efforts of this Administration have been pathetically small to the extent of only being a token strategy.
Dropping a few bombs here and there on empty fields and on the occasional Toyota pick up truck can't be considered to be terribly effective.
Russia has a larger military capacity at its disposal in Syria and are more aggressive so may be Obama is frightened of being shown up as an ineffectual wimp if he hands the Russians intel which they can use to good effect.
