What if Adolf Hitler had been assassinated in 1930? How would history have been changed?
I believe there would have been no Second World War in Europe. The more than 20 million troops who died in battle and more than 20 million civilians who were killed would have lived out their natural lives. But the consequences after that? A mixture of both good and bad..
Some say history might not have been changed all that much. They say some other Nazi, such as Goebbels or Goering, would have stepped into Hitler’s shoes. And that leader, they add, might not have made Hitler’s mistakes. A more capable leader might have won the war.
I don’t think so. The Nazi party was organized around the cult of Hitler’s personality. It wouldn’t have been so easy to find a substitute with his charisma. I don’t think any of the others would have had his ability to maneuver his way into the chancellorship, then leverage that power into absolute dictatorship and lead a reluctant German officer corps into war.
In the absence of Hitler, Germany might well have become an anti-semitic right-wing dictatorship anyhow, like Poland, Hungary and other European countries. The German government might have included a few Nazis. Germany certainly would have re-armed and resumed its place among the great European powers.
But the German generals did not want to go to war with Britain and France. We now know they would have attempted a coup if the Allies had resisted the remilitarization of the Rhineland or the annexation of the Sudetenland in Czechoslovakia. If Hitler had not tamed them, they would not have consented to starting a general war in Europe.
After the war, the German generals claimed they might have won if Hitler had not rejected their advice on strategy and tactics. But Hitler had a better strategic sense than they did. He recognized that without a dependable source of oil, the blitzkrieg tactic would have stalled, because it depended on large numbers of motorized vehicles moving quickly. He prioritized the invasion of Ukraine and the Caucasus, but the main objective of his tradition-bound generals was Moscow, the enemy capital.
No Hitler, no Second World War in Europe. What follows from that?
There would have been no atomic bomb in 1945 or perhaps. Without a Hitler, there would have been no reason to undertake such a project.
Only the United States had the wealth and industrial power to undertake the Manhattan Project, and even then, the project would not have succeeded without the help of European refugee scientists.
There probably would still have been a Pacific War between the United States and Japan. The cause of that conflict was the U.S. oil embargo against Japan to enforce a demand that Japan withdraw its forces from China.
Rather than comply with that demand, Japan seized the Dutch East Indies (now Indonesia), the only important source of oil in the Far East. The Japanese attempted to neutralize British and American forces by conquering the Philippines, capturing Britain’s Singapore base and bombing the American fleet at Pearl Harbor.
Even though the United States would have lacked an atomic bomb, there would have been no need for an American invasion of the Japanese islands. U.S. forces could have bombed and starved the Japanese into submission without an invasion and without nuclear weapons, probably with as much or more loss of Japanese lives than in the actual war.
