American global dominance was to be achieved by turbocharging "defence" expenditure and going to war with any country
Wars in Iraq and Afghanistan duly followed, together with the stimulation of several 'movements for democracy', i.e. funding and training mercenaries and local war lords to wage war on the enemy du jour, Libya and Syria being prime examples. PNAC also took great delight in prodding the Russian bear, nostalgic for the good old days of the Cold War. A notable adventure here occurred in Georgia, where what was in effect a joint Georgian/Israeli government had their ass handed to them when they provoked the bear once too often.
And in fact that's been the trend with all PNAC's adventures. Far from achieving American global hegemony their initiatives have bankrupted America's standing in the world, in moral, military and financial terms. Apart from the dubious success in Libya (that country being torn apart by internecine warfare and set back a generation probably qualifies as success for these pyschos) all the adventures have been unmitigated disasters. America's standing has fallen so much that various 'Red Lines' and final warnings have been blithely ignored by, inter alia, Iran, Syria and Russia with the US reduced to bleating helplessly about 'serious consequences'. Ukraine is the latest locus for their machinations and it's certain they'll get their ass handed to them again here. But at the risk of potentially provoking WW III. Meanwhile the reserve currency status of the dollar is on life support and when that finally goes - and it will - the economic consequences will be just horrendous.
So well done PNAC. You have weakened America beyond recovery, placed it on a trajectory towards Third World status, and strengthened the very 'enemies' you sought to weaken. Meanwhile those unfortunate countries who attracted your attention have suffered massive civilian casualties and ruinous infrastructural and economic damage.
If there's such a thing as karma these monsters would be hog-tied and fed to a drift of starving swine.
