Super truculent Bolton would be a terrible choice for anybody concerned with the long term strength and future of the USA. Unless the world is scheduled to end in 2015 or before, the American leadership must take to heart history's lessons and avoid the dangers of imperial overreach which destroyed world powers such as Spain and France. The US became the world's superpower in the first place by staying aloof and being the last power to enter general conflicts, not by trying to uphold the world single handedly and being to first to die and spend national treasure.
The money is drying up. Just as the USA needs to face facts concerning Social Security, we need to face facts about endless foreign adventures. National defense is a constitutional requirement, not world empire.
