Answer :
Answer: Cash and Carry
Explanation: Cash and carry is a policy that the US President Roosevelt officially requested at the Congress session on September 21, 1939 after the start of the war in Europe, that is, the German invasion of Poland. This led to the revision of the Neutrality Act, and enabled the sale of weapons and goods to allies while securing the transportation of these weapons and goods by Allied ships and paying in cash. America did not bear the risk of possible losses and damages during transportation.
The Lend-Lease Act was a program by which the United States Government helped and provided allies with the supply of weapons, military vehicles, warships, planes, oil, food, aid, etc. The program was signed by US President Roosevelt on March 11, 1941, and thus before the US's official entry into WWII, became an indirect participant in the war.
