There-in lies the rub. Modern war consumes munitions at a prodigious rate-unless you fight wars the liberal way and deliberate let your own people be killed to limit enemy casualties. Israel is a small country and doesn't come close to having the industrial base needed to sustain warfare at a level that would be decisive. They have to get replacements from us. It isn't certain that Obama would. Which means Israel would either have to fight at a low level intensity where the numbers against THEM would be decisive or the conflict would drag on without resolution -but the body count goes ever higher while fools who claim to be humanitarians thump themselves on the chest about how enlightened they are.
