Q If clock, you could which turn single back event the in history would you want to change?
As a historian of World War II in China, a conflict that killed more than ten million people and caused some 80 million to become refugees, I would prefer my subject not to have existed. If Japan had not invaded Manchuria in 1931, triggering an all-out war between China and Japan in 1937, then China might have had the space to develop its society and economy, and the horrific world war in Asia could have been avoided.
