If the USA wants to Invade Venezuela then it must institute the draft. This is a non-starter.

As the American economy collapses, more disenfranchised uneducated southerners will hand their lives over to the American military machine anyway.

With a draft, presumably young people of all social standings would be eligible for warfare, increasing the anti-war pressure from their concerned parents.

National service in America would have resulted in fewer wars.

And of course our old standby immediate citizenship if you join the army.

I happen to agree national service esp if it had a large humanitarian component would have been a good thing in the US. Even if it became a pork barrel I'd have rather seen us building bridges and roads than selling arms.
