Vietnam didn't end very quickly...at all.
I'm 100% for a draft. You probably get a less effective fighting force, but the general population thinks twice about yelling 'support the troops!' - cuz it might cost 'em a kid or two rather than just the price of a yellow ribbon at the mini mart.
In terms of investment/outcomes, it'd be hard to imagine a less effective fighting force.
But yes, if Kaitlyn and Dylan were facing the prospect of going to Kandahar instead of Cabo this shit would end right quick. Libtard apathy is being subsidized by a socially immobilized, spatially remote underclass.
