The United States is hated not for what we are but what we do in the world. 3. Oil can never be cited as the real motive behind the U.S. invasion of Iraq. 4. Sources of cheap labor, resources and profits — not promoting freedom — explain the 800 U.S. military bases around the globe and U.S. foreign policy since 1945. 5. The Israeli lobby in Washington does not serve this country's best interests. 6. The ''war on terrorism'' is only the latest propaganda tool to scare the public for other ends. 7. The proposed U.S. ''defense shield'' in outer space is an offensive weapon. 8. The purchasing power (adjusted for inflation) of the typical American family been falling for many years. 9. Big Business loves illegal immigration. 10. Most people experience no signficant upward mobility and the American Dream is now officially a myth.
