The argument can be summed up simply. Only a small percentage of Americans are carrying the burden of the war. This is unfair. More to the point, it has been impossible to get parents and college kids to give more than a passing damn about the war.I like this quote attributed to Talleyrand, "You can do anything with bayonets, except sit on them." These guys should be careful what they ask for.
The calls for a military draft are in fact calls for forcible enlistment in the anti-war movement, which has suffered greatly from its failure to recruit in the current voluntary political involvement model. The calls for a draft are nothing more than frustrated efforts to bolster the effectively non-existent anti-war movement to Vietnam levels by swelling its ranks with suddenly concerned suburban Americans.
