Many sources believe that General McClellan was too cautious to be a leader. He refused to proceed with anything until everything was fully prepared. He also did not know much about his enemy, which is crucial in any war. He underestimated them greatly. Hope this helps.
The US never wanted to join World War II so they isolated themselves from everything that was going on and tried to stay neutral (Over time, we sided with the Allies). Mainly, we entered due to the Japanese attack on Pearl Harbor. After the bombing, the US decided to declare war on Japan. Soon after, Nazi Germany's leader declared war on the US and then the US was officially in the war.
So, all in all, it was the bombing of Pearl Harbor on December 7, 1941.
