Shrub is a dry drunk. He stop drinking cold turkey. Any alcoholic who has never worked through whatever issues that led him to the bottle in the first place constantly assures those he purports to love, things will be better. This time.
An untreated substance abuser will tell those around them what they think they want to hear, then proceed and do whatever he feels like doing.
Shrub feels like picking a fight with Iran so he is doing it.
I wish someone would perform an intervention before Shrub blows up the planet.
