I believe that the best answer for this question would be the Lend-Lease Act of 1941. This Act allowed Congress to authorize the sale, transfer, exchange, or lease of weapons and supplies to any country that the President deemed vitally important to the United States' defense. This Act would assist the British and other Allied forces in winning future battles, but it was controversial. Hope this helps.
Obtaining a search warrant
Well it was mostly due to Henry Fords influence due to his new and innovative T-car which was cheap to make and cheap to get allowing nearly everyone in America get a car thus the auto industry sky rocketed helping people who had troubles with out cars to be able to use them regularly and helped them advance with new uses.
I hope this helps :3
