increased debate about the likelihood of success

increased opposition to the war

increased enlistment in the armed forces

The answer is The increased opposition to war. 

Nixon was not popular with his foreign policy of war to fight communists. During his term, people held numerous strikes that showed that the people were against its implementation. They don't want numerous soldiers to get involved and suffer. They also don't want people from foreign lands to lose their lives because of this.
