How did us leaders think people would respond to a military draft during world war i?

It was believed that people would oppose it, however, the opposite turned out to be true. The people of the country wanted to join and the war effort had mass support because it was considered to be noble to go and stop the oppression of Germany and Austria-Hungary who were terrorizing Europe.

Very useful. it is to learn because history repeats itself so learning about it those mistakes not happen again.
