You are by no means wrong. But outside of ancapistan types, I think everyone can say the governments job is to protect it’s citizens from would be invaders. With world tensions rising along with various other crisis’ it’s just the best move, being prepared for the worst and taking precautions.Trained vs untrained soldiers could be the difference between 500 casualties and 2500 (the infamous German school battalions of WW1 for example)
It’s one of the few actual necessary evils, unless your country is on the offensive of course.
I’m someone who studies history a lot.
Everything you said could be replaced with 1910-14 as the current year and you’d be pretty close to prevailing opinions of the day.
Wars need men. Well trained men ideally, but he who has the numbers usually wins.
In WW1 It took 3-6 months to churn through the professionals, in WW2 I don’t recall off hand but we’re looking at months. In Vietnam it did take 5 years yes, but that’s not the kind of war that Europe is or should be preparing for. In Ukraine it seems likely to be around 9 months, for Russia at least (unless you’re paratroopers then 3 days).
Outside of huge technological and leadership gaps you need the bigger army to win and that’s why conscription is the necessary evil.
