Emperor Hirohito should have been executed too... but he proved to be far more useful to us alive.
Yep,like when Patton proposed that the Nazi Party Officials should stay to run the bureaucracy,fire departments,water etc...Not the first time,nor will it be the last.Just an expediency, a necessary evil sometimes.And don’t forget those old scientists skulking the halls of Nasa in the fifties and sixties humming some old marching tunes.
