Every draft has been met by resistance, from the revolutionary war through the Vietname war. The riots during the civil war over conscription were just a fierce as anthing during the 60's (

If I remember my history properly, British conscription was also cited as one of the reasons for the revolutionary war. That however, did not stop George Washington from drafting soldiers to fight for the Union.
In every war in our history, with the exception of the 100hour persian gulf war and the current conflicts we have had to resort to the draft in order to man our battlefields. If the current conflicts continue as they have, with more enemy resistance and less popular support, we will undoubtedly reinstitute a draft of some sort.
