Next stop Baghdad! What do we do it it falls to IS? These IS guys—give them credit—yes they are savages and bloodthirsty but well organized and motivated—They do not mind dying for their cause. They have found a button deep within the Islamic state of mind—a vision of a new Caliphate to rule a new Islamic world of peace and harmony as poisonus as Communisms “World Solicalism”. Fight them now—or fight them later when they have A-bombs.
So, if the Shia get the upper hand no worries?
Doesn’t matter who wins, Sunni or Shia. Whoever gets the upper hand in the region they will be against the USA and try to destroy us (see Shia Iran for example).
