How did the U.S. help Britain before they officially entered the war?

Before officially entering World War II, the U.S. aided Britain through programs like Lend-Lease, which allowed the U.S. to supply military equipment and supplies to Allied nations. The U.S. also provided financial support to help Britain sustain its war effort and engaged in intelligence-sharing and military cooperation. Additionally, American naval vessels escorted British ships in the Atlantic to protect them from German U-boat attacks, reflecting a commitment to counter Axis powers without direct involvement in the conflict.
