berserker, if you throw out all the morality of it....
if bush is able to put into motion, US control of afghan, iraqi, and venez oil.... with iran completely surrounded for mccain/obama to force iran's hand...
he'll be viewed as the president that prevented an energy crisis and gained control of almost 1/3 of available world oil in less than a decade.
Again, throw out the moral aspect... from a strictly utilitarian position, it will be viewed as great.
