What's strange is that we here so little about WW1 and constant stream of movies and documentaries about WW2.
You can watch it here:
Trench Warfare: Chemical weapons, bi-plane battles, the first tanks, the first submarines used in battle. The beginning of the end of imperialism.
And the fact that the war actually ended because the soldiers refused to fight and the workers rebelled in the factories at home.
A disatarious landgrab by the major powers, the rich, the industrialist and the old world royalty.
This was the begging of everything we see today
