The text is a WWII - era address to Allied forces. The 1944 D - Day invasion at Normandy aimed to defeat Nazi Germany, match the goals in the address. Capturing Italian mainland was earlier, transporting to Britain was Lend - Lease, and Stalingrad was 1942 - 1943 Soviet battle. So the correct action is invading Normandy.
