The IRG are putting on a show... aimed at discouraging an Israeli attack. What's curious however, is the timing of this demonstration and the fact that the ideologically driven Revolutionary Guard control the missile and the nuclear program. We know these solid-fuel rockets can be used on short notice and with greater accuracy. So the question remains... are the Iranians rational or do they like to appear crazy. I don't know about anybody else, but to me... they certainly know very well to what level they are escalating this contest.
