Most Americans, if they think about our role in World War I at all, likely think we entered the conflict too late to claim much credit, or maybe they think our intervention was discreditable. Some might say we had no compelling national interest to enter the Great War; or worse, our intervention allowed Britain and France to force on Germany an unjust, punitive peace that made inevitable the rise of Adolf Hitler’s National Socialist German Workers Party. Had we stayed out of the war, they might argue, the Europeans would have been compelled to make a reasonable, negotiated peace, and postwar animosity would have been lessened.
Americans are easily forgetful of history, but we should not forget the First World War or our far from discreditable role in it. American intervention was decisive in the Anglo-French victory, a victory that deserves celebrating.
The war shaped the lives of some of America’s greatest soldiers and statesmen — including George Patton, Douglas MacArthur, Dwight Eisenhower, George Marshall, and Harry Truman — and was hugely consequential. Without exaggeration one can say that it was the war that made the modern world.
It was the war that set the boundaries of the modern Middle East out of the ruins of the Ottoman Empire. It was the war that saw the collapse of the Austro-Hungarian Empire, which had held together Mitteleuropa. It was a war that rewarded nationalism, which, perversely, had been the war’s original cause. It was the war that ended the Second Reich in Germany and witnessed the Bolshevik Revolution in Russia. It was a war that moved into the skies and under the seas. Men were set alight with flamethrowers and choked by poison gas. Infantry officers wore wristwatches to coordinate attacks. Trench coats became a military fashion accessory. And a Europe that could still see angels hovering over battlefields in 1914 was shell-shocked by 1919, full of doubts about the old chivalric ideals, prey to callow superstitions and pagan political movements.
It was the apparent collapse of the old ideals that helps explain what has become the popular view of the First World War — that it was a senseless, stupid struggle, the ultimate charnel house, the watchword for the obscenity and absurdity of war. The casualty lists were indeed horribly long. The victory that was won was indeed horribly mismanaged. But such casualty lists were inevitable in a modern war of European empires; and the mismanagement of the peace was not the soldier’s folly.
