Winston Churchill
Secretary of State for War and Air: 1919–1921

Lloyd George called a general election for 14 December 1918. During the campaign, Churchill called for nationalisation of the railways, a control on monopolies, tax reform, and the creation of a League of Nations to prevent wars. He was returned as MP for Dundee and, though the Conservatives won a majority, Lloyd George was retained as prime minister. In January 1919, Lloyd George moved Churchill to the War Office as both Secretary of State for War and Secretary of State for Air.

Churchill was responsible for demobilising the army, though he convinced Lloyd George to keep a million men conscripted for the British Army of the Rhine. Churchill was one of the few government figures who opposed harsh measures against Germany, and he cautioned against demobilising the German Army, warning they might be needed as a bulwark against Soviet Russia. He was outspoken against Vladimir Lenin 's Communist Party government in Russia. He initially supported using British troops to assist the anti-Communist White forces in the Russian Civil War, but soon recognised the people's desire to bring them home. After the Soviets won the civil war, Churchill proposed a cordon sanitaire around the country.

In the Irish War of Independence, he supported the use of the paramilitary Black and Tans to combat Irish revolutionaries. After British troops in Iraq clashed with Kurdish rebels, Churchill authorised two squadrons to the area, proposing they be equipped with "poison gas" to be used to "inflict punishment upon recalcitrant natives without inflicting grave injury upon them", although this was never implemented. He saw the occupation of Iraq as a drain on Britain and proposed, unsuccessfully, that the government should hand control back to Turkey.
