On May 10, 1940, a little more than 8 months after World War II had begun, British Prime Minister, Neville Chamberlain, resigned. On the same day, Winston Churchill was asked by King George VI to form a new government, only after Lord Halifax, the foreign minister and the frontrunner to replace Chamberlain, had declined the post of Prime Minister. Had Halifax assumed the post, it would have critically affected Britain's war time conduct and would have resulted, most likely, in a British exit from the war, around June 1940. Indeed, employing Artificial Intelligence, as a tool to estimate the odds of such an early exit, yielded a result of approximately 75%, given the historical data, that supports this assessment.

A British early exit would have set the world on a radically different historical course, echoing through the 21st century. The book examines the various paths of such alternate course in detail and scope, which have never been done before.

Against the background of many of the key events of the war, the book examines the global implications of Britain's early exit on Germany, the Soviet Union, the United States, Britain, Italy, Japan, Israel, NATO, the United Nations, and other countries, regions and institutions.
Among others, the book explains why, following a British early withdrawal from the war under Halifax's premiership:

1.the Soviet Union's odds of defeat, amid the Nazi onslaught in mid-1941, would have been in the realm of probable (around 80%), given all the factors, discussed and assessed in the book;

2.Nazi Germany would have seized and had control of most of western and eastern Europe (extending well to the latter part of the 20th century and, possibly, beyond);

3.the world would have looked strikingly different. A world without D-Day, the State of Israel, the Berlin wall, NATO, the United Nations, the Internet as we know it today, or without Vladimir Putin's rise to the post of president of the Russian Federation in 1999 and without the bloody war between Russia and Ukraine, initiated by him in 2022;

4.the Japanese would have not attacked Pearl Harbor and Germany would have not declared war on the United States, thus eliminating any basis for American involvement in WWII;

5. there would have been no spread of communism, no cold war, no Korean war, no Vietnam war, no race for the atomic bomb, no bombings of Hiroshima and Nagasaki and a substantial delay in many of the scientific discoveries, which evolved from the war.

The book, analyzing pure, uncontested data, raises the question, with sober hindsight, whether Churchill's heroic defiance in 1940 truly saved the world and whether Lord Halifax's hypothetical "Yes" might have spared it untold agony and would have been better to Britain and the world.

Lord Halifax's renunciation of the premiership is remembered, if at all, as a footnote of political hesitation. Yet, as the book shows, it is, probably, the most consequential refusal in modern history.
