"Dominating the world" is not the issue here. Preservation of the nation is at stake. As Dr. Sowell points out, we do not have the luxury of sitting behind our two ocean barrier any more New sophisticated weapons have made them obsolete. if we are not prepared to immediately thwart the efforts of an enemy, whoever it may be, we will not have the time, as we did in WWII, to ramp up for combat. It'll be all over before that!
