Based on the OP most of the neocons would be running Iran. Building nukes and being friendly with terrorists and North Korea is a threat to world peace.
It worked in Italy, Germany and Japan...shocking all three are friends today!
And there'd have been no need to be on the streets taking hits. Retire the troops to a significant base, secure it, offer training, material support and occasional air support and win the hearts and minds of the masses. If you can do that in Japan after nuking it you can do it anywhere.
"What difference" "does it make?"
