Pretty much everything that could, went wrong on the Nagasaki bombing mission.
Japan was investigating nuclear bombs during World War II, but didn’t have the materials.
The 70th anniversaries of the bombs dropped on Japan, August 6 and 9, will bring more discussion of whether that should have been done. I think this argument gets it mostly right: Truman and his advisors had lived through six years of terrible war; a new weapon had just been tested after a grueling development; there was no way they would not have used it. Today’s arguments of alternatives to the bombings look at the decisions from the point of view of comfortable lives (usually) in America or Europe not threatened by war. And a point of view informed by the 70 years since the bombs were dropped. None of that applied in 1945. And that’s why we built international organizations afterward to make sure that such a war never happened again.
Pakistan may be becoming less externally belligerent in order to deal with its internal problems.
