Take your toys and go home
You know what? Do it! Take your toys and go home. Pull your military in, become an insular xenophobic self-facing terrorized dictatorship, please. .
Without American interference and arms dealing, South America might unite into a power bloc that might finally, FINALLY allow those countries to install the government they want. The African Union would have a chance to clean up their continent, and bring true reform to the shattered nations that are leaving millions in abject poverty.
The EU would be able to continue along it's crippled, but evolving eurocracy, and perhaps even set a new standard for governance and quality of life in the world.
The Asian nations all seem to be trucking along quite happily no matter what anyone anywhere says, and that will never, ever change.
Russia will become a superpower again, who cares? Good for them! They have the resources, and the people...eventually they'll either become a relatively open society, and deal with their own internal crime problems, or fracture, and not be a worry to the rest of the world.
The middle east will tear itself apart, and the Indian subcontinent will probably help. Nothing you, or I, or anyone anywhere could ever say or do will stop that. The only thing middle eastern nations hate more than each other is anyone trying to stop them from destroying each other.
In short, the world doesn't need the US. The once great nation that spearheaded a wonderful concept known as democracy, but got torn apart by unchecked capitalism is, outside of it's ability and desire to bully the world...now irrelevant.
We don't need your soldiers, there are millions of them worldwide working for organizations like the EU, AU and the UN that are eager to help, and we don't need your money, because your country doesn't have any anymore.
So, for the love of all that is right in the world, please, impeach your president and sue his government, or just do the world a favor, and hurry up and shatter into a collection of bickering nation states, so we can get on with the business of providing the former US with economic aid, and bring them into the light of democracy.
