During all the wars before this, warfare was organized somewhat and was fought in fields and deserts. This war was different because it was fought in the jungle. This started “guerilla warfare”. The native people who were used to the jungle started to use sneak attacks and booby traps. This threw the U.S. off because we had not trained to fight like this.
At this time in U.S. history people were outraged at the military for going somewhere we didn't belong. They believed that soldiers were dying for no true cause. People were also protesting African American rights. The African Americans were sent to the front line to fight where people would die the most.
When you are 18 years old you are required by law to sign up for the draft. This meant that kids our age new that as soon as they were out of high school they were going straight to the military. This system angered people because the did not get a choice to fight or not to fight for someone else's belief.
During the war African Americans were supposed to be “free” but they still found themselves dealing with segregation, even in the military. African American troops were all put together and sent to the front line to fight. This was not fair because this was the most dangerous place to be in the war.
