Entering World War One against Germany was America's greatest blunder of the 20th century. America had no reason to join the 3-year-old struggle. By sending two million doughboys to the Western Front, America shattered the battlefield stalemate and won the war, allowing Britain and France to impose a devastating peace on Germany, thus igniting toxic German cries for revenge.? ? Absent America's entry into the war, the exhausted combatants, however unhappily, would have had to drag themselves to a negotiating table and there make a peace of compromise. There would have been no victor, no vanquished, no Versailles Treaty, no reparations, no German demands for revenge, no Hitler and surely no World War II and even no Cold War. ? The tale of how America stumbled into war is told by?America's Greatest Blunder. It chronicles America's journey from sensible neutrality to its war declaration. It then describes how legions of doughboys were mobilized and trained and how they won the war, giving victory to Britain and France - thus launching the young 20th century on its course of decades of unprecedented violence.
