Senior US government officials are confirming Iran will acquire at least the SA-20 air defense system. The -20 and the -21 systems, so called "double-digit" air defenses, are extremely capable, to the point most analysts consider their presence to preclude the operation of conventional strike aircraft. The range is great enough to even pose a problem for logistical aircraft like AWACS and tankers. Yes, the F-22 seems able to engage them, but that puts a big ol' dent in the hopes any of you may have been holding for Israel to step up and rid us of those turbulent priests.
