The United States has pursued empire since early in its history, but it was the Soviet collapse in 1991 that enabled Washington to see the entire world as its oyster.

The collapse of the Soviet Union resulted in the rise of the neoconservatives to power and influence in the US government. The neoconservatives have interpreted the Soviet collapse as History's choice of "American democratic capitalism" as the New World Order. 

Chosen by History as the exceptional and indispensable country, Washington claims the right and the responsibility to impose its hegemony on the world. Neoconservatives regard their agenda to be too important to be constrained by domestic and international law or by the interests of other countries. Indeed, as the Unipower, Washington is required by the neoconservative doctrine to prevent the rise of other countries that could constrain American power.
