Which act enabled the United States to provide military aid to Allied nations before entering WWII?

• A. Cash-and-Carry Act
• B. Lend-Lease Act
• C. War Powers Act
• D. Monroe Doctrine

Answer: (B)

Providing military aid to Allies before the United States enters WWII rests on giving the president the authority to lend or lease defense materials to countries whose defense is vital to U.S. security. The Lend-Lease Act did just that, authorizing the president to lend or lease weapons, vehicles, aircraft, and other defense articles to any government deemed essential to U.S. defense. This allowed Britain, the Soviet Union, and others to obtain substantial military aid without requiring immediate cash payments or direct American involvement in combat, effectively expanding aid while the U.S. remained officially neutral. It marked a shift from earlier limits like cash-and-carry, which required cash up front and transport by the recipient, to a broader, loan-or-lease approach to support Allied efforts. The other options don’t fit: cash-and-carry was a more restrictive policy that still limited arms provision; the War Powers Act deals with presidential authority during wartime and came much later; the Monroe Doctrine addresses hemispheric dominance and noncolonization rather than wartime aid.
