Historians rethink key Soviet role in Japan defeat

By SLOBODAN LEKIC

As the United States dropped its atomic bombs on Hiroshima and Nagasaki in August 1945, 1.6 million Soviet troops launched a surprise attack on the Japanese army occupying eastern Asia. Within days, Emperor Hirohito’s million-man army in the region had collapsed.

It was a momentous turn on the Pacific battleground of World War II, yet one that would be largely eclipsed in the history books by the atomic bombs dropped on Hiroshima and Nagasaki in the same week 65 years ago. But in recent years some historians have argued that the Soviet action served as effectively as – or possibly more than – the A-bombs in ending the war.

Now a new history by a professor at University of California, Santa Barbara seeks to reinforce that view, arguing that fear of Soviet invasion persuaded the Japanese to opt for surrender to the Americans, who they believed would treat them more generously than the Soviets.
