Is it treasonous to urge resistance to a war once America is in it? Most Americans opposed our entry into the First World War but once Wilson sent our men, some argued it was no longer OK to urge resistance. It was 100 years ago, in June of 1918 when socialist former presidential candidate Eugene Debs was put in jail for continuing to speak out. The irony of fighting a war “to make the world safe for democracy” while clamping down on freedoms was not lost on him or Republican US Senator “Fighting Bob” LaFollette of Wisconsin, whose colleagues sought to expel him for his continued outspoken opposition to the war. On this show, Smithsonian journalist Erick Trickey talks about what lessons from 100 years ago still apply today.
