What is the source for this mythological Yankee altruistic spin?
Without the U.S., the innocent facing terror and extermination across the world are on their own.
Except when other states go it alone..... France is rather prime example of a single player making contemporary intervention in NW Africa. Just doesn't make your news circuits.
Or, your fanatsy also neglects when the USA is a prime actor to enable and even assist in genocide. Guatemala, Nicaruagua, El Salvador, Indonesia, and even to the previously mentioned Cambodia.
Hell, the USA was a prime player in crippling and detering a sufficient UN force in Rwanda.
Iraq is in the state is due to US criminally aggressive warfare into Iraq, followed by a decade of thorough incompetence.
By long standing historical precedent, the USA is most certainly not THE global saviour.
