Iran definitely is an issue. When you have a leader who threatens the destruction of a neighboring country and is not condemned, you know there is a concern. If Abadingdong would drop the bomb on Israel, how long would it be before he would go after other neighboring countries? Who would be next, Saudi Arabia? For that reason, I can understand the desire for them to get a bomb, as a deterrent.
However, the instability of Egypt, Libya, Tunisia and possibly Pakistan and Syria makes this entire region a bomb, primed for explosion. Why would the world want to have this region primed with nuclear weapons? Are we suicidal?
Having unstable nations run by religious zealots whose religion encourages its believers to kill unbelievers (potentially with nuclear weapons) is a recipe for disaster. If one believed they would go to heaven by killing millions, why would one not drive a bomb into a neighboring country and explode it? No need for expensive and complicated delivery systems, just drive a truck.
The world better wake up before we face Armageddon! We must NOT allow these nations to get the bomb! This region is not the same as most other countries that currently have the bomb. With Russia, France, England, we had leaders who understand the concept of "mutually assured destruction." With Abadingdong, there no concern with other human life and the more of his enemies that he destroys the higher his position will be in heaven.
The UN (for whatever good it can do) and the rest of the civilized world needs to join together to prevent these nations from getting these very dangerous weapons.
