What should we do with Iran?

This author has decided to make a statement, that basically, the US should keep the ability to produce and use nuclear arms away from Iran. He saw this is Iraq four years ago as a threat, and had agree to enter the country in order to stop it. The author believed that the Iraq war was caused by “competition for the region's abundant reserves of fossil fuels, (b) demographic pressures arising from the region's high birthrates, (c) the growth of radical Islamism and (d) the determination of Iran to acquire nuclear weapons”., however he sees the nuclear weapons as a huge threat to the safety of the US. Iran is starting to develop the technology and the resources that it could be assumed to be used on one target, Israel, a hated enemy but a great US ally. An attack of this nature could make a huge problem occur between these two countries, and the US would be stuck in the middle of it and become a threat. Furthermore, the United Nations has decided to not allow force or intervention to stop the nuclear arms development, which the author believes is the wrong decision. He thinks that diplomacy on this great of an issue between the great of rival nations will never work, force behind however could produce results. He wished that the US gets immediately involved in this issue either by examining the facilities and not letting their production continue, or but battleships close enough to where their air missiles can pin point and destroy nuclear facilities, removing the danger of this threat. The author even criticises Bush for not doing this, only because he is worried about his own reputation.
Personally, I would not like to use force, because we are already spread insanely thin, no like we were before the Iraq War. However, if we saw that development was clear and that a clear launch against Israel could happen, I would not use force, but show off my power. I would place battleships near and let Iran know that if they do decide to launch against Israel, we would quickly respond to them, hopefully detering a massive loss of life.
