This statement is insane. Both cities were so devastated that Hirohito surrendered to the allies, and he was a man who was prepared to fight the allies to the death in the streets of Japan. Take this fact together with the fact that today's nukes are far more powerful than the early A-bomb, and Israel will for all intents and purposes cease to exist as a nation for years to come, (and this assumes that only one bomb will hit). Iran must be stopped.
Japan surrendered to the US because Russia was bearing down on them. The power of A-bombs is vastly overestimated by most civilians, and the power of radioactive fallout even more so.
