An obscure "What-If" of history: Had Goeben not passed the Dardanelles, it was very possible Turkey would have remained neutral in WW1. Absent Turkey, the Allies lost their only supply route to Russia. This loss was so serious that in 1915 Churchill felt it imperative to assault the Dardanelles. The resulting debacle was the principal reason Churchill was ousted from the Admiralty. Because of Goeben, the Russian armies starved for food and materiel. The Czar fell and the Bolsheviks took over.
