France at that point was not a military superpower. Or even a superpower at all. When WW2 started, France was barely out of ww1 shellshock.
I don’t think people realize how fucking BRUTAL ww1 was on France.
There are still areas today (not a lot thankfully) that are considered inhabitable today because of the vast amount of bodies (animal and human), unexploded ordinance, chemical damage… en.m.wikipedia.org/wiki/Zone_rouge
Entire forests and villages razed. And I mean, razed down to the ground. Nothing left standing. Not a tree, not a brick.
When I was a kid growing up in my village, the one advice our parents gave us almost every day was ‘if you find something shiny, don’t touch it.’
Last year I was having a walk in the forest after a good rain and found, half buried in the mud, a German grenade, right in the middle of a path I used to ride my bike almost every day. A friend lost a hand when he found one when we were kids.
BTW, this is what Gazan kids are going to deal with, Ukrainian kids too. Anyone who supports Israel, anyone who supports Russia, supports the future suffering of the kids.
