A) the decision to overturn the results of a state election INCORRECT This option is incorrect because the President does not have the constitutional authority to overturn state election results. Elections are administered by the states, and the federal government's role is limited to overseeing federal elections and ensuring compliance with federal laws. The Little Rock crisis was not about election results but about enforcing desegregation in public schools.
B) the decision to declare war on a foreign nation INCORRECT This option is incorrect because the power to declare war is vested in Congress, not the President. While the President can order military action in certain circumstances, the formal declaration of war requires congressional approval. Eisenhower's action in Little Rock was a domestic law enforcement measure, not a declaration of war against a foreign nation.
C) the decision to enforce a judicial ruling CORRECT This option is correct because President Eisenhower was referring to his decision to enforce the Supreme Court's ruling in Brown v. Board of Education. When Governor Faubus resisted the integration order, Eisenhower federalized the National Guard and sent federal troops to ensure compliance. This action exemplified the executive branch's duty to enforce judicial decisions, as outlined in Article II of the Constitution, and reinforced the principle of federal supremacy.
D) the decision to desegregate the military INCORRECT This option is incorrect because the desegregation of the military was an executive order issued by President Harry Truman in 1948, not Eisenhower. While Eisenhower supported civil rights, his action in Little Rock was specifically about enforcing the Supreme Court's school desegregation ruling, not about military policy.
