Soros, worth $7bn, spoke at the launch of his new book, The Bubble of American Supremacy, much of which is devoted to hammering US foreign policy under Bush. He said Bush 'uses the war on terror as a pretext to pursue a dream of American supremacy that is neither attainable or desirable'-Bush's defeat in 2004, he said, would been seen around the world as a rejection of a doctrine that holds that the US 'will not tolerate any rival globally or in any region' and that it 'has the right to engage in preventive adventures abroad'.
