Put the German Kaiser on Trial in 1920?

Kaiser Wilhelm II abdicated on 18 November 1918 at the end of World War I and took refuge in The Netherlands. The Treaty of Versailles, signed in 1919, stipulated that he should be brought to trial. However, the Dutch refused to extradite him. The Allies kept trying, as evident in this editorial from the Pittsburgh Press of 19 January 1920, but he lived in comfortable exile until his death in 1941.
