A sample from a novel idea I'm toying with...

"The United States, as the most powerful economic and military force on the planet, became the leader of those countries that chose to reject what they saw as an attack of cultural imperialism. The United States, as the leader of this coalition of the unwilling, became its voice. And after six months of stalling, the United States, as the most vocal in its refusal to comply with the system of ethics as laid out by the Galactic community, became the first and so far only nation to be invaded. Three days later, when there was no longer a US Army, US Navy, or US Air Force, nor a US government to command them, the aliens simply took over, and over three hundred years of American Independence came to an end."
