“In September 1918, the German government issued a diplomatic protest, complaining that the Model 97 Trench Gun was illegal because “it is especially forbidden to employ arms, projections, or materials calculated to cause unnecessary suffering” as defined in the 1907 Hague Convention respecting the Laws and Customs of War on Land. When the Americans rejected this, the German high command then threatened to execute any soldier caught with a Trench Gun or even just Trench Gun shells. General Pershing replied that, henceforth, any Germans caught with flamethrowers or saw-bladed bayonets would be lined up and shot.”
Hmpffff… if you are going to ban inhumane weapons… I will agree that the shottie is an unsportsmanlike weapon to use on humans… but so is gas, artillery, land mines, aerial bombardment, RPGs… you name it. And today the yields are up by orders of magnitude. I hope we have the stomach for the future our leaders are preparing for us.
