WW1, because america was not involved was shipping mustard gas heavily too.
Something that turned chads into skin rotting incels.
And on that note.
America has never even won a single war.
WW2 was won by the brits and the commies, USA joined late and were actually supplying weapons to both sites beforehand.
Entire US army vs some farmers for the Vietnam war: Farmers won
Entire US military vs some dudes rummaging around the sand: Dudes in the sand won.
The only person the USA can brag about is osama, one dude hiding in a sand house, no longer a leader.
