Thus even today, many, perhaps most, Americans completely deny that America is engaged in empire building at all - despite the presence of US troops in more than 100 "sovereign" nations. America has practiced a new form of neo-colonialism which involves indirect corporate hegemony and covert rather than overt military actions in many cases. Even Iraq was to help Iraqis enjoy the fruits of democracy!
It is the indirect/covert/ideological model of US neo-colonialism which is particularly corrosive as it can seemingly co-exist side by side with all the laudable claims to virtue contained in the Declaration of Independence. In some ways the old European model of colonialism which involved direct military/poltical rule was more obvious and more honest - and easier to oppose/resist.
"Global corporations" are almost beyond all governance. Military contractors are not subject to the usual military disciplines. And most American's would be genuinely appalled if they knew the full extent of what the CIA et al routinely engages in.
The sadness is not the the US is worse than (say) Nazi Germany or the Stalinist Soviet Union. Of course it is not. The sadness is that such noble ideals have become so debased - which is also why we have to be careful how the EU develops if it ever does become a "harder" world power. "It's a mystery to me - the game commences, For the usual fee - plus expenses, Confidential information - it's in my diary..."
Maybe, of maybe not.
Wikipedia: Revision and replacement of the Articles of Confederation
Rakove (1988) identifies several factors that explain the collapse of the Confederation. The lack of compulsory direct taxation power was objectionable to those wanting a strong centralized state or expecting to benefit from such power. It could not collect customs after the war because tariffs were vetoed by Rhode Island. Rakove concludes that their failure to implement national measures "stemmed not from a heady sense of independence but rather from the enormous difficulties that all the states encountered in collecting taxes, mustering men, and gathering supplies from a war-weary populace."[13] The second group of factors Rakove identified derived from the substantive nature of the problems the Continental Congress confronted after 1783, especially the inability to create a strong foreign policy. Finally, the Confederation's lack of coercive power reduced the likelihood for profit to be made by political means, thus potential rulers were uninspired to seek power.
