1. The war in Europe ended with a win of the Allied forces. The Soviets were the ones that gave the first big blow to the Germans, and once that happened, the Germans were gradually pushed back and in a defense mode, instead of the attack mode they preferred. The US joined its European allies, and together with the French and British forces, it managed to take over the west coast of the Germans. With Allied forces coming from both direction, the Germans found themselves in a very bad situation, and little by little they were losing their ground, eventually resulting in their defeat, and the end of the World War II.
2. The ''Europe first'' military strategy had big impact on the war in the Pacific. The US and its allies, Canada and Australia, were fighting with Japan. The progress was slow, island by island, with big losses of military personnel during the process. As the US wanted to end the war with Japan as quickly as possible, and with as little casualties on its side as possible, especially because they were going to be needed in Europe, a big decision was made. The decision was to drop atomic bombs on Japan. While this was a controversial move, the US did what it intended, dropped two atomic bombs on Japan, and effectively ending the war in the Pacific, immediately turning to the European front afterward.
