Seen interviews from the other side from lonely old men who haven’t been drafted but wanted to sell their lives to provide monetary help for their younger relatives, pay for school neccessities for their grandchildren etc, since they’ve already had the best of their time on the earth and are open to give something back. Without going an inch deeper into what they are signing up to do, that’s one kind of motivation that can put amateur elders into trenches in the context of a foreign country war. Had none relatives doing that, thankfully, but seen the same pattern with my gramps in their last years, and can imagine a future orphan-crushing-machine headline of some Jonh H. Lawnmover going into another war because their daughter can’t pay a hospital bill after a short stay if I assume the same mentality exists in the US in spite of borders.
