Answer:
Germany got out of WWII by being conquered. The red Army raised the Russian flag over Berlin on 2/5 1945. Hitler and his wife Eva Braun had taken cyanide and he had shot himself on 30/4 because he would never surrender to the Russians.
Germany was surrounded by the Allied powers USA, Britain with commonwealth and France to the west from 1944 and the Soviet Union to the east approaching since 1943.
In 1943 the Allies had taken back North Africa and had began to invade Italy and pressed on the Germans ally Italy, until the Italian opposition overthrew and arrested Mussolini. Although there was an Italian puppet government in northern Italy relying on Germany for defense which weren't beaten until 1945.
In 1944 the western Allies invaded Normandy and liberated France from the Germans. From 1943 Germany's economy had suffered a lot form allied bombing and could no produce enough machines and weapons to fight a war against the world's super powers anymore, and losing oil supplies led to fuel shortage. Qualified military leaders thought that there was no hope anymore, and tried to get rid of Hitler, resulting in Hitler dismissing many and taking more control himself, with much less military knowledge. Hess had alone tried to negotiate peace with Britain. Late 1944 Hitler launched one last desperate offensive in the Ardenner forest (aka "The Battle Of The Bulge") using his fierce Waffen-SS forces supported by tanks. Despite having initial success the Germans were defeated and the lines returned to normal.
Meanwhile on the eastern front the Soviets were advancing closer and closer to Germany. In late April and early May 1945 the final campaigns of the western theatres of war were concluded. On 16/4 1945 the battle of Berlin began as the Red Army breached German defenses. On 30/4 following Hitler's suicide Karl Dönitz became Reichspräsident and Commander-in-Chief and started the capitulation process in a manner to avoid falling into Russian hands with risk of deportation to Siberia. On 1/5 German forces in Italy surrendered. On 2/5 German forces in Berlin surrender. On 4/5 German forces in north-west Germany, Denmark, Netherlands and Bavaria surrender. On 6/5 German forces in Breslau surrender. On 8/5 German forces in the Channel Islands surrender. On 7/5 Chief Of Operations Staff High Command Alfred Jodl unconditionally signed surrender on behalf of the German armed forces on Dönitz' orders. The following day Field Marshall Wilhelm Keitel was asked to repeat the act on order from Stalin. These events resulted in Germany being out of the military part of WWII. Local troops could continue in skirmishes for a few days, not being aware of the peace announced. On 8/5 the end of the European war was celebrated in many countries.
