Did Iran just prevent WWIII?

The highest tech missile defence as designed and deployed Israel and the US was just shown to be completely inadequate against even third rate missiles. Iran didn't send its newest and nicest missiles. It sent some old dust collectors and of the 7 aimed 5 hit the most highly defended military base in the world. Suddenly Europe and Taiwan and North Korea are aware of the US and Israel's military shortcomings and the the much vaunted US navy is suddenly a floating target.
