Why Have Isolationists Been Dissatisfied with U

Why have isolationists been dissatisfied with U.S. foreign policy since 9/11?

A) The United States has not exhausted nonmilitary means such as economic sanctions and weapons inspections before using military intervention in other countries.
B) The U.S. military has been involved in too many other countries when its purpose should be to function as a shield in homeland security.
C) The United States invaded Iraq without a postwar plan to institute democracy, which should be one of the prime goals of U.S. intervention in another country.
D) The United States has taken actions of which its allies have disapproved and will now have difficulty getting help from them in the war on terror.
