Bluster and ranting

Iran is not now, has not been, and unless action is taken to force regime change, will not be at any time in the future, a responsible enough entity to be allowed any access to nuclear power.  

Don't believe me?  Then listen to them.

Recently, their military had a parade, showing off the weapons that they have, and making threats against other nations.  In particular, one truck carried a banner that read, in both English and Iran's native Farsi, "Israel should be eliminated from the universe."

Does this sound like a nation responsible enough to be trusted with the capability to create nuclear weapons?  

During that parade, their president announced that sanctions had failed.  He announced that those who believed that "economic and scientific sanctions could break down our revolution and our nation" were wrong, and added that the world had lost hope.  

First of all, the world is well aware that sanctions have failed.  They likely would have succeeded were it not for Russia ignoring them to help Iran build "civilian" nuclear power plants.  Second, any sane government would be afraid, not happy, that Western civilization has lost hope that sanctions could succeed.  Once diplomatic options have been exhausted, all that's left is attack, and we're already over there, right next door to Iran.  Israel is even more determined than we are that Iran not become a nuclear power.

But wait, there's more: during the parade that showed off long range missiles (at least, long range enough to reach UN bases in the Middle East, as well as Israel), Iran's president vowed that they're ready for military attack, and will strike back at the slightest hint of hostilities.  He says "If anyone allows himself to commit even a tiny offense against Iran's legitimate interests, borders, or sacred land, our armed forces will break his hand before he can pull the trigger." 

The UN is in agreement with us that "legitimate interests" is doublespeak for "nuclear ambitions."  It's also pretty clear that it could very well count for "wiping Israel from the face of the earth with those nuclear ambitions."  And if that statement isn't a threat for preemptive attack the moment they feel they can win, I don't know what it is.

And there are still people out there, in the United States, the European Union, the United Nations, and NATO that think Iran isn't a threat, that they genuinely want peaceful use of nuclear energy to create clean, efficient, electrical energy for their people.  I think these people need to listen to just a little bit of Iran's bluster and ranting.  A little bit goes a long way to convince reasonable observers that Iran's regime is neither sane nor responsible enough to be allowed access to nuclear technology.
