I wouldn't call a test of a solid fuel missile with an 8000+ mile range, that took ten months to prepare and involved the rebuilding of the missile, and which was then launched downrange for only half of the range it would need to reach its target -- a particularly impressive flexing of our muscles.

I'm not in any way suggesting the test was a failure, but given all those factors that are totally unrealistic in any kind of actual hot-button scenario, I sure wouldn't call it convincing.
