The US government has formally denied that it has any acknowledgement of civilisation beyond its borders. The announcement came in response to the We The People website, which initially promised to address any petition that gains 5,000 signatories.
Two petitions called for disclosure of government information on aliens and an acknowledgement of any contact. The White House responded that there was "no evidence that any civilised life exists outside our country."
It is understood that this stance is the reason for the baseball tournament being called the World Series, despite having no participating teams from outside the US. Similarly, US military forces operating in overseas bases are provided with unlimited bubblegum, soda and McDonalds to protect them from the alien cultures and customs which surround them.
Before being allowed abroad, the few non-military US citizens that feel the need to travel overseas are told to make no allowance whatsoever for being in alien lands. Complaining about the food being too healthy, hire cars with too much acceleration and hotel rooms having only one TV is encouraged, while arrogance and phony friendliness towards fellow travellers is compulsory.
"Many scientists and mathematicians have looked... at the question of whether civilised alien life could exist outside the United States, and have come to the conclusion that the odds are pretty high that somewhere among the billions of aliens on the planet, there could be pockets of civilisations just like ours," wrote Overseas policy expert Phil Larson of the White House Office of Science and Technology Policy.
"Many have also noted, however, that the odds of us making contact with any of them - especially any of similar intelligence to us - are extremely small."
