In 1938 there were many who could see the dark clouds forming and assembling above but no one knew the extent of the horror that was going to unfold over the next seven years. The world is facing a similar situation in 2013.

The world should not think for one minute that the Iranians want a negotiated settlement just as Hitler never wanted anything but total and absolute control of the world. The West always has a hard time reading the Muslim world.
