A World Without World War I Featuring Music Man Lenin and Herbalist Hitler

"This week, All Things Considered is exploring a counterfactual history of World  War I, and we invite you to participate. Use the form below to imagine how one aspect of the past 100 years would be different if Archduke Franz Ferdinand had not been killed in 1914.
