At the end of April 1945 the Soviet forces occupied Berlin, the capital of the German Reich. American and British troops did not enter the city until two months later on 4 July, the French forces participating initially with only a small unit. During those first two months, the Soviet Union was the sole occupying force, reorganizing life in the city in line with its own ideas and objectives.
The credit for defeating the Germans should go to the Soviet/Russians. The Allied Expeditionary Force was formed in 1944 as a British-American expeditionary force. When US./British forces arrived in Berlin. the Soviet forces were there waiting. The vast majority of German casualties were inflicted by the Russians, not the Americans/British.

Italy became a war zone. For 18 months the Allies fought the Germans up the peninsula, wreaking untold devastation throughout the land. The Allies took Naples in October 1943 but reached Rome only in June 1944, Florence in August, and the northern cities in April 1945.
The Allies took the northern cities of Italy in April 1945, and the Germans tendered the unconditional surrender of the Berlin garrison on May 2, 1945 — to the Russian army.
Nobody won the war with Germany in North Africa. The war in Europe was decided in Europe. The Germans suirrendered to the Russians, and then the Russians waited two months for the Americans to get there.
