I’d say it’s preferable to the memorial that would have been held for the million or more who would have died in a homeland invasion. Hiroshima and Nagasaki should never be “celebrated” as good things: They were grim choices that were only slightly better than the other grim choices before this nation in 1945.
I guess we will never hear from them, “We are deeply sorry that our leaders made this necessary.”
It was grim, but Japan, surely, would have used the bomb had they harnessed the technology first.
Rough and Ready Island near Stockton, CA. was where the invasion was to shove off.
