Iranian Is Going to Build Atomic Bombs

Iran is dead set on manufacturing nuclear weapons. They have also promised and pledged to their own people on more than one occasion to blow Israel off the map. Indeed with nuclear warheads and their current high-tech weapons arsenal, they could deliver a swarm of ICBM type missiles into Israel actually do it. Luckily the do not have nuclear warheads yet, but soon will.
The United States has said the Iran cannot have nuclear weapons as the Iranian leadership is currently sponsoring international terrorist organization and is somewhat of a radical and fundamentalist regime.
Some military strategy folks have gone so far to say that we must take out 2/3 of the Iranian army that balances the field after the war in the region, so they cannot attack Iraq. Additionally we must destroy all the late high-tech toys, weapons they have been buying to kill people with. Next we must stop, the nuclear weapons manufacturing by force, since they will not. Is there another way?
Many decry military intervention especially because we already have two-wars going on; Iraq and Afghanistan. Yet these folks who condemn the thought of force to prevent Iran from starting WW III have yet to state what should be done, so I say to these anti-war folks;
"Now then, what is your solution to achieving a peaceful Iran another way. They told the UN to stick it. They told us if we try to stop them they would use Hezbollah to attack Western Targets and civilian populations using international terrorist acts. They have promised to blow Israel off the map. They fund international terrorist organizations. And they have been sending in insurgents to Iraq to kill US troops."
So, unless they have a better way to stop this and know something no one else knows about negotiating with terrorists, please speak now. Because last time I checked once the terrorists decide to cut off someone's head, sharpen the blade and start the video camera, well let's just say it is all down hill from then on. And I sure as hell would not want to be in range of a Chinese rocket with a nuclear warhead on it fired by order of an Iranian fanatical fundamentalist leader, would you?
