I'm in my 70s, so the military would only want me when the Russki tanks are rolling down Pennsylvania Avenue and they are handing out panzerfausts to the women and children.
Only Gen Z would be in the 18-24 age range, and most of them voted for Biden.
Of those in the 18-24 age range, the majority would not qualify for military service.
I don't discount Armstrong, and I think that this would be very interesting to watch happen. I think it might well backfire on the Democrats.
As I count it, the US has been involved in 32 wars/military actions since the end of WW2 - and that doesn't include Ukraine.
That there will be a war has been a safe bet for 70+ years.
