Why would you say that? They aren't conscripting at all. There's not even a whiff of anyone suggesting we need to activate the draft.
Conscription refers to involuntary military service, and there hasn't been a hint of that since Vietnam (it worked out sooo well in Vietnam, with a crazy high incidence of soldiers killing their own superiors).
Even in voluntary service, recruiting is way less aggressive than it used to be. Growing up in the 80s/early 90s you were inundated with recruiting efforts, on radio, television, and even as a pretty aggressive part of school. My kid has not been nearly so exposed to recruiting efforts. Now we have a third of people going in compared to 1990 (and they are still turning down about 25% of applicants).
So I don't know where you are coming from, but involuntary service in US isn't vaguely in sight and even if you mistook voluntary service for 'conscripts', even that is at a 40 year low and still turning away people... Hardly seems 'deseperate'
they are participating on conflicts all over the world and are missing their targets for personnel, despite aggressive campaingns on social media kids.
this tells me enough about their involvement and possible future role in the next world war.
TBF, we aren't even remotely close to the scale of international conflict seen in the 2 world wars. You have to be deeply ignorant to think otherwise. Again, we're not even close, not even like a tiny fraction in terms of scale.
