When one is an acolyte of the Marxist/socialist, command-and-control approach to governance, nothing aggravates more than that which is beyond one's command and control. Couple that tendency with an all-encompassing narcissism and a facility for prevarication and what do you get? A United States president more than willing to put Israel's very existence on the line so as not to weaken his chances for re-election in 2012.
