The reason Japan attacked Pearl Harbor
Not a bad one at all.
Historically it seems pretty accurate.
But meanwhile, as to

it seems the USA population is becoming more
involved in paying lip-service to Veterans,
and giving some support in many small ways.
But increasingly, the majority do not really
appreciate nor value past military service.
