Operation Unthinkable: Winston “Warmonger” Churchill's Secret Plan to Invade Russia in 1945

In the spring of 1945, Winston Churchill asked his military chiefs to prepare a secret plan. That was nothing new. The hyper-energetic Churchill was always coming up with plans, some clever and some crazy.

In early 1945, America was focused on finishing off Germany and then taking down Japan. But Churchill's gaze beheld a darkness descending upon Europe. What would happen with a Red Army occupying its heart? Stalin had already reneged on earlier agreements that Poland—the reason that Britain had gone to war in 1939—would be free. Instead the Polish government was packed with Soviet supporters while Polish resistance fighters ended up in NKVD prisons. Romania, Hungary and Czechoslovakia were under Soviet control, and Greece and Turkey appeared under threat. Thus British planners devised “Operation Unthinkable,” an apt name for what would have been World War III. What could be a more unimaginable task then trying to devise some way for Britain—broke and exhausted after two world wars—from launching a preventive war to defeat the Soviet colossus? Yet even if Great Britain was losing the “Great” by 1945, orders were orders, and military planners are accustomed to devising responses to the most unlikely contingencies. So they gamely went to work, and by 1945 had worked out a plan. The attack would begin on July 1, 1945, to allow operations before the winter weather arrived. They assumed that Soviet intelligence would detect Allied preparations and thus make an Operation Barbarossa–style surprise offensive impossible. Thus the Allies would have a tough fight right from the start.

Operation Unthinkable envisioned an offensive by the Anglo-American armies, plus a Free Polish contingent (the Canadians were also informed of the plan). These forces would breach the forward Soviet defenses in Germany. The expectation was that the Soviets would then mass their armor along the Oder and Neisse rivers, which the Soviets had made the new border between Germany and Poland. A gigantic Kursk-like armored battle would be fought around Stettin. If the Allies won it, they would advance to a 250-mile-long line between Danzig and Breslau, where they would halt to avoid exposing their flank to a southern attack from Soviet forces in Czechoslovakia. Ironically, the plan bore many resemblances to Hitler’s Operation Barbarossa, which also counted on defeating Soviet forces near the Russian border to avoid a prolonged campaign deep inside that vast nation. “The planners believed that if they could secure this line from Danzig to Breslau by autumn 1945, it might be enough to bring Stalin to heel,” writes author Jonathan Walker in his book Churchill's Third World War: British Plans to Attack the Soviet Empire, 1945 . Total war against Russia—months before the first atomic bomb was dropped on Japan—was an outcome that no one wanted.

Nonetheless, the Allied planners found themselves in the same trap that destroyed Napoleon and Hitler. How do you make Russia surrender if it doesn't want to? If defeating the Red Army on German soil wasn't enough, then the only alternative was to advance eastwards into Poland and then Russia. “The planners now paled at the thought of the enormous distances the Allies would have to penetrate to secure victory,” Even as the working camps were being destroyed, Britain contemplated rebuilding a German army to fight the Russians. “One of the most contentious issues in the Unthinkable plan was the use of German forces within the Allied camp,” But rearming ex-Nazis paled in comparison to an absolute foundation of Operation Unthinkable, which was that the United States would join Britain in attack on the Soviet Union. Roosevelt, and initially Truman until he knew better, were convinced that it was possible to work out a postwar accommodation with Stalin. They were wrong, but they didn't know that in the spring of 1945. And there was still the victory with Japan to be won—for which Soviet help was considered essential. In other words, America had just finished a crusade in Europe against Nazism. It wasn't about to embark on a crusade against Communism just yet. The rock-bottom fact of a war that would have dragged the world into World War III is this: Operation Unthinkable called for the democratic nations of the United Kingdom and the United States to initiate a war with the Soviet Union. The justification would have been the need to roll back the Soviet empire from its German and Eastern European conquests. Read more ...
