Well, in respond to the Russians delaying the S-300 missile system deal, Iran plans to develop an air defense system that is comparable to and even more sophisticated than the advanced Russian S-300 system. In respond to the U.S. planting missile systems (for attack and defense purposes) ,including eight Patriot missile batteries, in Gulf area, Iran is launching a domestically-built air defense system to counter the ballistic missile threat. They built anti-helicopter missiles, advanced ballistic missiles, etc... Khomeni might annouce some military advantage . If Iran became nuclear, Arab states would want to be nuclear. ( UAE and Saudi have already started their nuclear activity--- some are discussing even buying the nuclear bomb). Iran is dragging the region to war and arms race.
