I don't believe that, I don't see why anyone else would.
Nobody is worried about Japan's ambitions nowadays. You do know what happened to Japan's imperial ambitions, don't you?
And the mullahs are very good at creating that atmosphere, aren't they?
The Soviets didn't both threaten others with annihilation AND run external terror networks so they couldn't be held accountable in case of attack.
No, the mullahs are giving out every signal that they intend not just to acquire but to USE nuclear weapons. Already, before they have them, they are intent on using their dark shadow to inspire fear and obedience in others:
Try picturing a Shiite-Muslim mega-church in a huge downtown tent, with separate entrances for men and women and separate seating (with the women all covered in black). A huge poster of a nuclear mushroom cloud surmounts the scene, with the inscription oh zionists, if you want this type of war then so be it! link
