Sandy.. no amount of political posturing will motivate the folks in this nation to a just and total world war short of another 9/11 disaster.
It is a sad truisim that other nations and political entities can kidnap, rape and murder our women, kill our troops piecemeal on foriegn soil, attack, seize and nationalize our business intrests, spy upon us, rob us blind, default on treaties and attack our allies without fear of significant reaction from the 'sleeping giant' that is America.
But bomb our citizens in their beds, blow up some buildings, take out a blue city.. the wrath of the American nation will be aroused. Nothing less will do it.
Just as FDR needed peal harbor to unleash the American Juggernaut.. so it remains today. George missed the chance to get it done with the support of a huge number of other national entities... and he pissed it away.
