Gorbachev's new policy changes included allowing Western goods, ideas and services into the USSR in hopes of reviving the economy.

What was the Lend-Lease Act?

The Lend-Lease program was initially targeted to help Great Britain who informed American officials that the war had nearly bankrupted the country, and they would no longer be able to pay for supplies in 1940.
