Without commenting on accuracy, I think this short sentence deals with the past few years in a tidy, summary fashion: "But apparently just an accusation is enough to justify preemption."
Although the suggested Iranian invasion of Iraq would be suicide, I am in agreement that is a sacrifice the Iranian leadership is quite prepared to ask of its youth. Certainly, the US would be happy to eventually oblige in a non-discriminating manner. But could Iran even pull it off? If Iran "massed" a few armoured divisions, wouldn't that take time, and would there not be the detectable tell tale signs that go with it? Whats the flight time from Missouri to Iran, because it seems to me that is the measure of the window of opportunity to assemble and execute, figuratively and literally.
