1) How did Hitler and the Germans eventually get officially defeated?
2) How did WWII actually officially begin?
3) What different strategies did they use compared to WWI?
4) What event made Japan get involved in the war?
Through my research, I was able to learn that World War II was officially started when Germany invaded Poland. There were many preparations that Hitler made before invading Poland, such as the Munich Agreement and creating an air force and a larger military. Once Germany invaded Poland, Britain and France had no choice but to declare war on Germany, thus starting the second world war.
In the first world war, both sides used trenches and fought in "trench warfare". Also, Attrition Warfare took place in the first world war, which is where a side attempts to win a war by wearing down the enemy of personnel losses and resources. Through the losses of soldiers and resources, the enemy is supposedly suppose to surrender because they simply cannot continue fighting in the war anymore. For World War II, the U.S. air force was superior, they had more troops, and were able to win the war by overrunning the enemy. Even though the Germans had more advance technology, they did not have as many troops, so they eventually lost.
