Should he apologize? Mr. Obama’s predecessors had good reasons to avoid Hiroshima. None wanted to be seen by American voters as apologizing for a decision that many historians even today believe, on balance, saved lives. And there were worries about how such a visit would be viewed in China, South Korea and other countries in Asia that suffered from the brutal World War II killing machine that was Imperial Japan. Nope. The decision to drop the bomb saved many American lives, so for that reason alone, it was justified. Also, there's nothing magical about nukes, they're just big bombs. Dropping one nuke on Hiroshima is no different than fire bombing Tokyo with thousands of incendiary bombs. War is all hell, hence the Japanese reaped what they sowed. UPDATE And now we know: Barack Obama called for a world without nuclear weapons on Friday as he became the first sitting U.S. president to visit the site of the Hiroshima atomic bombing. ... Obama did not apologize for the U.S. actions and instead paid tribute to "all the innocents killed across the arc of that terrible war," saying that "their souls speak to us" and "mere words cannot give voice to such suffering."
