This.
And remember, on a bad day in WWI, 20,000 men would go over the top, get mowed down, and 10,000 would run back.
10,000 letters would soon be sent out to 10,000 sets of parents. The generals would remark, "I say, that went decidedly poorly!" and call for another 10,000 men to be sent to the front lines from the reserves to try it again a couple days later.
The battle would be covered with a couple of lines in the papers, talking about their gallantry.
Life is still not worth what we think it should be worth. Countries are still being lead by aggressive military types, crooks, megalomaniacs, and dangerously incompetent fools. But our ancestors had it worse.
