The problem lies with in the Iranian government. They know what they need to do and thats allow UN weapons inspectors full access to the facilities. But i still dont think that thats going to be enough for the US or Israel. Because i feel that Iran would use it if they had it. Thus just think that might do something is reason enough to take it out. Its just like that mole you got removed from your back. And why was removed? because that same mole could turn into cancer and then kill. Was the guaranteed outcome? No, but just having the knowledge of what might happen was enough to have it removed. Thats what we are trying to avoid with Iran. By blowing up the Nuclear plant we will know 100% for sure that they are not going to make the bomb. Then Iran can go back to what ever it was doing before this whole fiasco.
Plus once they have it they are sure as heck not going to give it up. Just look at the whole Pakistan/India situation. No can do anything because they both have the bomb. Neither willing to back down for fear of what the other wont do. which in this case is disarm. Same with North Korea. We cant do anything too bad otherwise Seoul might look like Hiroshima.
Being a poor county and having the bomb is that like that bully we all had in school, unless you were that bully, that would take your lunch money. You pay him your lunch money for fear of what he might do, but you wont tell on him either for the same reason.
Something to think about: What would the geopolitical structure of the middle east be like today if Israel had not destroyed Iraq’s nuclear reactors?
