Despite the Neutrality Acts, the United States did provide some assistance to Britain and its allies. This assistance included the sale of war materials to Britain on a "cash-and-carry" basis. This meant that Britain had to pay for the war materials in advance and had to arrange for their own transportation. The United States also began providing military aid to Britain through the Lend-Lease program, which allowed the United States to lend or lease war materials to Britain without requiring immediate payment.
The United States also provided Britain and its allies with military intelligence. This intelligence included information on German troop movements, ship movements, and air strikes. This information was vital to the Allied war effort and helped them to win the war.
In addition to providing military aid and intelligence, the United States also gave Britain financial support. This support included the provision of loans and credits to Britain, which helped to keep the British economy afloat during the war. The United States also provided food aid to Britain, which helped to prevent famine in the country.
The United States' assistance to Britain and its allies was vital to the Allied victory in World War II. Without this assistance, Britain may not have been able to continue the war and the outcome of the war could have been very different.
