Actually, the main reason there was a draft in WWII was because they needed to organize the entry of men into the armed forces. Virtually everyone wanted to go, they couldn't take them all at once and why create a new system when you've already got one ready? So, they took in a percentage of volunteers (mostly those who wanted to volunteer for special duty, like paratroops) and the rest were told to wait for their number to come up.
Happened that way with my grandfather. He was an art school student and treid to enlist during the week after Pearl. He was told to wait for his number, and it was called in '42. He went ashore at Anzio and fought in Italy his whole time.
Hold the bus,after Pearl Harbor they wanted to fight,before Pearl Harbor not a chance in hell. After 9\11 there were a lot of young and not so young Americans who wanted to go defend their country and unlike the WWII generation,these kids were NOT educated and schooled in the values of America. On the contrary most of them have grown up in a society ruled by the mainstream media and an education system that continuosly preaches how BAD our country and our system is to the rest of the world !!!
