This is where Iraq plays a pivotal role; Iraq lies in-between Iran and Syria. Iraq can secure its own boarder and prevent the movement of people and goods between two terror friendly countries.
In a recent tech central article I read this.
The "unilateralist" Bush administration is also setting up a sister organization to the PSI called Caspian Guard. Caspian Guard is ostensibly a three-way alliance between the United States, Azerbaijan and Kazakhstan for the integration of several interlocking program elements, namely airspace and maritime surveillance and control systems, reaction and response forces, and border control.
What might be Caspian Guard's deeper mission? Take a look at a couple of maps, one of Azerbaijan's neighborhood and one of Kazakhstan's. What do they have in common? Both are central Asian states with coasts on the Caspian Sea, and both either share a border with or are across the water from Iran. Caspian Guard is to Iran what the PSI is to North Korea -- a cage in the making, constructed by the Bush administration's State Department. Look for several other US-leaning states in the area, such as Uzbekistan and Turkmenistan, and possibly even Turkey, to either join the Caspian Guard or cooperate with it in significant ways. The US will begin to encircle Iran, the world's most dangerous remaining Islamic state, the way it is attempting to encircle North Korea, all to strangle their nuclear proliferation programs and over time halt their nuclear programs altogether.
Additionally, Caspian Guard gives member states access to US training and tactical knowledge and the assurance of friendly relations with the world's sole superpower in exchange for assistance in dealing with some of the axis of evil's charter members.
While I will admit that the state department's idea is far more advanced than mine (as it should be), mine is just a small part of what they are trying to do.
