Winston Churchill supported the use of poison gas against the Kurds

The argument

Critics who argue that Winston Churchill was not a hero point to his documented advocacy of using poison gas against rebellious peoples in the British Empire, which they regard as evidence of a willingness to inflict cruelty on colonial subjects. As Secretary of State for War and Air in 1919, during unrest in the newly controlled territory of Mesopotamia (modern Iraq), Churchill expressed support for using chemical weapons against rebellious tribes, including Kurdish and Arab populations, famously writing that he was 'strongly in favour of using poisoned gas against uncivilised tribes' and dismissing squeamishness about it. He argued that gas could be used to spread 'a lively terror' while, in his framing, not necessarily being lethal. The argument treats this as revealing a deeper attitude. To advocate deploying chemical weapons — a category of warfare widely regarded as especially abhorrent — against colonial populations resisting British control, and to describe those populations as 'uncivilised tribes' deserving of such treatment, reflects, critics argue, both a casual readiness to inflict suffering and the racial contempt that underpinned imperial rule. That the gas was contemplated as an instrument of terror against people fighting foreign domination compounds the charge. From this standpoint, a man who enthusiastically advocated chemical warfare against subject peoples cannot be remembered simply as a hero, whatever his later role against Nazism. His attitude toward the empire's subjects, expressed in his own words, reveals a side of his record that the heroic legend obscures. Because Winston Churchill supported the use of poison gas against rebellious peoples including the Kurds, this argument holds, he was not simply a hero.

Premises

Counter-arguments

Defenders and historians complicate the charge on two points. Some read Churchill's 1919 memo — which the argument itself quotes as envisaging gas "not necessarily lethal" — as favouring lachrymatory (tear) gas rather than lethal chemical weapons, and note that the plan was not in fact carried out in Iraq. The historical record is more contested than the bald accusation implies. They add that even granting the remark reflects imperial-era contempt, a single reprehensible position from 1919 does not by itself settle the verdict against a career that included the wartime leadership of 1940. This, they argue, supports the "flawed hero" reading rather than the flat conclusion that he was "not a hero."

Rejecting the premises

[Rejecting P1] Historians note the 1919 memo the argument quotes as envisaging gas "not necessarily lethal" is read by some as favouring tear gas, and that the plan was not in fact carried out — complicating the charge. [Rejecting P3] Even granting imperial contempt, defenders argue a single reprehensible 1919 position does not negate the wartime record, which is exactly what is contested between "not a hero" and the "flawed hero" verdict.
