Ron Paul is the only candidate with some chance left who will not continue American imperialism.
The American people so decide also with their vote on who are the candidates of their parties already if America will be a peaceful member of the world community or continues to invade countries.
With this vote the people of America decide if they want to be a friend or an enemy of at least parts of the world. And the people around the word will know soon how the majority of the American people want their government to act.
