IIRC, one of the sad “collateral damage” events of WWII was the Nagasaki bomb
wiping out the largest contingent of Christians in any Japanese city.
I’ve know at least one Japanese that teaches at a Christian college
He said his father (a Christian) didn’t “cooperate” with the Japanese government
during WWII, and endured plenty of grief for it but did survive the war.
(My friend didn’t want to go into great detail; I was suprised his
father wasn’t executed or worked-to-death for his resistance to
the Japanese militarists).
I had never thought of that before this article. Another element of tragedy in the dropping of the bomb.
