While the military war made most of Ireland ungovernable from early 1920, it did not actually remove British forces from any part. But the success of Sinn Féin's propaganda campaign reduced the option of the British government to deepen the conflict; it worried in particular about the effect on British relations with the US, where groups like the American Committee for Relief in Ireland had so many eminent members. The British cabinet had not sought the war that had developed since 1919. By 1921 one of its members, Winston Churchill, reflected: What was the alternative? It was to plunge one small corner of the empire into an iron repression, which could not be carried out without an admixture of murder and counter-murder... Only national self-preservation could have excused such a policy, and no reasonable man could allege that self-preservation was involved.
