This has massive strategic implications for the US. The US couldn't protect its bases in the middle east from a middle power like Iran and in fact its bases were the reason that its "allies" in the gulf were attacked. Iran would have no reason to attack those allies otherwise. The US has also shown that Israel is the only ally that it really cares about.
Japan, South Korea, Philippines and Australia are taking notes. Prediction: there is not going to be a war over Taiwan - Taiwan will gradually come to a Hong Kong like agreement with China.
