Anyway like I said the reality of it is unworkable. In terms of culture, in terms of infrastructure, in terms of Compliance ("they'll go to JAIL!"
I have bad news folks, those are already fkn full!) and it simply won't happen.
You would maybe - MAYBE - get a small pilot programme going in a few specific areas in around 5 years, that would run for a few more years, then never be expanded.
Funnily enough though they have "more quietly" added in the "it won't necessarily be military..." part.
So if it is real, I think the actual intention is to use unpaid/very cheap young "national service" labour to fill out understaffed health services with carers, porters and support workers. IF it ever happens and you fast forward a couple of decades, that's what 90% will be doing. Conscripted care of the elderly. A whole different type of dystopia, but at least no ones getting shot.
