Operation Unthinkable: The Third World War: British Plans To Attack The Soviet Empire, 1945, is an stellar book about Operation Unthinkable, which was a plan hatched by Winston Churchill’s staff in the the near end era of the second world war. The plan called for an invasion and destruction of the Soviet Empire, or as the plan said, to enforce the will/wrath of the British and American Empire, at the end of the war. The plan would of used American, British, French, Polish resistance fighters, and the last remaining elements of Nazi Germany’s Military. Jonathan Walker goes into great detail about every little crevice in the creation of the plan, such as when he described the climate in Britain near the end of the war, as well as many factors which affected the creation of the plan. He goes into a similar amount of detail for every part of the plan, from it’s creation to its later use as a contingency plan during the cold war. The book progresses nicely, and no knowledge about the early cold war(mid-late 1940s- early 1950s) is required. I heavily recommend this book to anyone interested in history, but readers interested in history around World War Two-The early cold war in particular will find this book very interesting and fun to read.
