In theory, the 13th amendment should've made conscription illegal in the U.S., but the Supreme Court, doing what it often does, which is to be incompetent, declared that the 13th amendment doesn't apply to conscription. The following text is what makes up the 13th amendment:
Section 1. Neither slavery nor involuntary servitude, except as a punishment for crime whereof the party shall have been duly convicted, shall exist within the United States, or any place subject to their jurisdiction.
Section 2. Congress shall have power to enforce this article by appropriate legislation.
Technically speaking, conscription constitutes "involuntary servitude," but yeah, apparently the Supreme Court didn't give a fuck in the 1900s. Anyway, I'd like to say that I oppose conscription in all instances, as it is unnecessary and has never worked. Our biggest example of this being the case was Vietnam. Hundreds of thousands of soldiers and maybe marines were drafted to fight in a war that we didn't even win in. Approximately 58,000 troops died for nothing. For nothing.......
One could say that the Selective Training and Service Act of 1940, signed by FDR and instituted the first peacetime draft in U.S. history, was good for America and without it, we would've either lost the war against the Axis powers, or, alternatively, we would've taken longer to defeat Nazi Germany and Japan.
Bullshit. Our military in 1939~1940 already had about 10 million service members. The draft increased that number to 16 million. We only suffered about 300,000 casualties. I'm getting off-subject, but I hope you guys get my point....
Conscription is not necessary, especially not in the 21st century, where militaries have significantly increased their dependence on their naval and aerial warfare branches. The U.S. is no exception.
Instead of conscripting people into the army and/or the marine branch of a military, the U.S. and other nations should just rely more on their aerial and naval warfare branches. Nowadays, the navy and air force win the wars for their respective nations.
