US HEGEMONY IS MAINTAINED BY PEOPLE MOTIVATED BY WHAT THEY SEE AS ITS UNARGUABLE NECESSITY, AT ANY COST. FOR ALL SORTS OF REASONS: ECONOMIC, TRIBAL (PERHAPS NOT ALL FOR THE SAME TRIBE), IDEOLOGICAL, ECOLOGICAL, EXISTENTIAL. THEY SEE THE PRESENT AS A CHANCE FOR A UNIHYPERPOWER TO CEMENT ITS STATUS AS SUCH. SOMETHING NEVER DONE BEFORE IN HISTORY. THIS WON'T END WELL.
