="What is "Nuts!" in Farsi?
Ahmadinejad perhaps?"
The proper pronunciation is "Ahmadthenutjob".=
is it your ability "to exercise one's wits"?
Instead, please, tell me sincerely:
Why USA, Russia, China, France, Israel can have nuclear bomb but Iran - not?
Thus far, none of those nations have called for the destruction of another sovereign nation by any means possible. Also, they aren't run by religious zealots who are intent on the return of their messiah (of sorts). When the Israelis elect the extreme Right wing that calls for the destruction of the Palestinians (Cananites) and the expansion of Israel from the Nile to the Euphrates, then I'll question their ability to safely wield nuclear weapons, until then, M.A.D. works wonders.
because by word and deed Iran has left no doubt that they will *use* the nuclear weapon as soon as they get it... plunging the world into a chaos which even Russia will not benefit from.
Nobody would expect any of the countries that you have listed to start lobbing nukes at one-another. On the other hand who would be surprised if Israel or Saudi Arabia went up in a puff of smoke from an Iranian nuke? Who would be shocked if Hezb'Allah ended up with a couple?
In my opinion, the difficulty with Iran having nuclear weapons is their religious fanaticism. With the countries that you have listed, the doctrine of mutually assured destruction works. Not so in a society that believes that death by fighting Infidels is a certain ticket to Heaven -- that all the world must come under Sharia Law or die.
Iran supports non-state actors as well, such as Hezb'Allah, who would certainly have the bomb if Iran did. Iran should not have nuclear weapons for the same reason Chechnyan rebels should not. In fact, if Iran had nukes, Chechnyan rebels and all other good Muslim groups would probably soon have them.
They would use it the first chance they got. They would use it without fear of retaliation and they would use it without remorse. Indeed, they would celebrate the loss of Innocent lives. The one thing that unites all religions from Atheists to Buddhists, is that according to Islam, we are all Infidels, therefore, legitimate targets of Islam. Even Sunni Muslims are apostate in the Shia's eyes. The wholesale death and destruction would be inconceivable.
