I found this article by John Mauldin to provide a better overview of Iran than much of what's given in the news. It seems to me to provide some better explanation of a lot of the "why" for events in the region. http://www.1913intel.com/2008/07/24...an-holding-the-center-of-a-mountain-fortress/ "For Iran, its ultimate problem is internal tensions. But even these are under control, primarily because of Irans security system. Ever since the founding of the Persian Empire, the one thing that Iranians have been superb at is creating systems that both benefit other ethnic groups and punish them if they stray. That same mindset functions in Iran today in the powerful Ministry of Intelligence and Security and the elite Islamic Revolutionary Guards Corps (IRGC). (The Iranian military is configured mainly as an infantry force, with the regular army and IRGC ground forces together totaling about 450,000 troops, larger than all other service branches combined.) Iran is, therefore, a self-contained entity. It is relatively poor, but it has superbly defensible borders and a disciplined central government with an excellent intelligence and internal security apparatus. Iran uses these same strengths to destabilize the American position (or that of any extraregional power) around it. Indeed, Iran is sufficiently secure that the positions of surrounding countries are more precarious than that of Iran. Iran is superb at low-cost, low- risk power projection using its covert capabilities. It is even better at blocking those of others. So long as the mountains are in Iranian hands, and the internal situation is controlled, Iran is a stable state, but one able to pose only a limited external threat. The creation of an Iranian nuclear program serves two functions. First, if successful, it further deters external threats. Second, simply having the program enhances Iranian power. Since the consequences of a strike against these facilities are uncertain and raise the possibility of Iranian attempts at interdiction of oil from the Persian Gulf, the strategic risk to the attackers economy discourages attack. The diplomatic route of trading the program for regional safety and power becomes more attractive than an attack against a potential threat in a country with a potent potential counter. Iran is secure from conceivable invasion. It enhances this security by using two tactics. First, it creates uncertainty as to whether it has an offensive nuclear capability. Second, it projects a carefully honed image of ideological extremism that makes it appear unpredictable. It makes itself appear threatening and unstable. Paradoxically, this increases the caution used in dealing with it because the main option, an air attack, has historically been ineffective without a follow-on ground attack. If just nuclear facilities are attacked and the attack fails, Iranian reaction is unpredictable and potentially disproportionate. Iranian posturing enhances the uncertainty. The threat of an air attack is deterred by Irans threat of an attack against sea-lanes. Such attacks would not be effective, but even a low-probability disruption of the worlds oil supply is a risk not worth taking."
