I hope this helps you. If not an entire page of information for your question is on History.com- Berlin Airlift
Explanation:
After World War II, the Allies partitioned the defeated Germany into a Soviet-occupied zone, an American-occupied zone, a British-occupied zone and a French-occupied zone. Berlin, the German capital city, was located deep in the Soviet zone, but it was also divided into four sections. In June 1948, the Russians–who wanted Berlin all for themselves–closed all highways, railroads and canals from western-occupied Germany into western-occupied Berlin. This, they believed, would make it impossible for the people who lived there to get food or any other supplies and would eventually drive Britain, France and the U.S. out of the city for good. Instead of retreating from West Berlin, however, the U.S. and its allies decided to supply their sectors of the city from the air. This effort, known as the “Berlin Airlift,” lasted for more than a year and carried more than 2.3 million tons of cargo into West Berlin.
Germany fought Russia/USSR and France in both world wars. Both Italy and Japan where aligned with Third Reich in WW2, but fought against Germany in WW1. Italy did align itself with the German Empire in the years leading up to WW1, so that is the best answer out of all of these. However none of them are truly correct.
