Hiroshima + Nagasaki
When the U.S. dropped the world’s first nuclear bombs on Hiroshima and Nagasaki, some 150,000 Japanese were killed instantly, while some 200,000 died in the following year. It was the biggest and fastest mass murder the world had ever witnessed. The U.S. claimed that it was the only way to end the war quickly, as an invasion of Japan would have cost many more lives. Others insist, however, that Japan had already signaled its willingness to surrender long beforehand. Read here about the hidden history of this war crime.
David Irving, one of the most-knowledgeable historians on WWII, states Hiroshima bombing was not justified (2009).
