How did roosevelt's lend-lease act shift us foreign policy away from isolationism?
a. it lent arms to allied forces and allowed them to pay later.
b. it allowed the us to sell arms to belligerent nations.
c. it put us bases on german territory.
d. it put us bases on british territory.

The correct answer is letter A.

Lend-Lease Act  corresponded to a natural development of US policy, favorable to the allied cause in the conflict then largely confined to Europe. Previously, the supply of war material to the Allies was based on the principle of cash-and-carry, ie cash payment. The exhaustion of UK dollar reserves by the end of 1940, however, made it necessary to revise this policy in light of the concept that support for the United Kingdom was vital to US national security.
