Here is a Press TV (Iranian English language TV) video report on Iran's successful launch of short-range missiles overnight. The report says it was done as a part of "War Games" being conducted by their military.
This is all part of their "cat and mouse" game on inspections. They say one day they will allow inspections but then the next day do something militaristic like this to prove how tough and defiant they are. Iran's totalitarian government is not one that can be trusted. President Obama is "whistling past the graveyard" if he thinks they can be believed or trusted in the slightest.
