More than half a century has passed since the end of World War II, but many topics related to this war are covered with a veil of mystery. Among them is the history of Lend-Lease, the assistance that the United States provided to the countries of the anti-Hitler coalition. The book offered to the reader for the first time in Russian publishes the work of Edward Stettinius, who was responsible for organizing Lend-Lease, as well as the opinions of modern historians on the role of Lend-Lease in the Great Patriotic War.
