With all of the talk about the agreement between Iran, the US and 5 other world powers, one key aspect has been largely overlooked. Iran may never have tried to develop nuclear weapons had it not been for the US invasion of Iraq in 2003. That ill-conceived and unwarranted act placed US troops at the Iranian doorstep and, since George W. Bush labeled Iran as part of the “axis of evil”, it implied that Iran could be invaded next.

So if you’re the leader of Iran, what would you do to prevent such an invasion? The most reliable deterrent is nuclear weapons.

Why else would the US not have invaded western Pakistan when we knew that its madrassas were inciting Muslim extremism? (We knew that because we helped create them to fight the Soviet Union.) Pakistan had nuclear weapons and the missiles to reach Europe…possibly the US. Nuclear weapons are the ultimate deterrent – the ultimate equalizer.

The threat of our invasion has led Iran to the brink of becoming a nuclear power. Iran will not give up that deterrent without receiving something in return. That’s why the nuclear agreement negotiated between Iran and the world powers is the best possible outcome for everyone. The US, Europe and Israel get the assurance that Iran cannot complete their nuclear program. And Iran sees an end to paralyzing economic sanctions.

The agreement has already been approved by the United Nations. It should be approved by Congress.

If not, Iran will become a nuclear power within a matter of months. Moreover, China, Russia and other nations who have their own economic problems will tire of the sanctions against Iran and will resume trading with them.

And what if the US and/or Israel are foolhardy enough to carry out a series of military strikes on the Iranian nuclear installations? That will not only result in international condemnation and make the Iranian people even more anti-US. It will give Iran incentive to quickly rebuild the program and to finance anti-US, anti-Israeli terrorism throughout the region and the world. And the US will likely become embroiled in a war across the entire Middle East.

Considering those alternatives, the negotiated agreement looks a lot better, doesn’t it?
