Or a Japanese subway....
‘’Or in a Japanese subway’’.<, Yup. Grand Dad always used to say that in a city in a large building or subway was where gas would be most lethal. He’d say “You don’t need an army. Just one person with a canister’’.
And yet with far less education and money the London and Madrid subway and train attacks killed far more people with plain old explosives, to say nothing of killing even more people with even less money and some box cutters.
Chemical weapons have no business being included in the same category as nuclear and biological weapons as "WMDs"
