We don't have a military advantage of Iran? Really? I am not sure if you've noticed, but the US and Israel have some of the most advanced militaries in the world. If the US were at war with Iran, the Iranians would need the help of some other powerful nation to have anything that even resembles a chance of winning.
Hate to break it to you, but technology isn't everything. Just ask the Taliban.
First of all, the leak I was talking about was about technology, supposedly robbing Israel and the US of a particular technical advantage over the Iranian military. If technology is not everything, then the importance of that leak was greatly overstated; if technology matters, the importance of the leak is still greatly overstated.
That being said, while it is true that coordination, tactics, and strategy can outweigh technical advantages, better technology confers a tactical advantage to an army. The greater the difference in two armies technologies, the more pronounced the tactical advantage is. The Taliban did not see anything resembling a victory when the US attacked Afghanistan; they survive now by hiding in caves, and their overall strategy is based on intimidating civilians.
If you want to point to a case where superior technology did not result in victory, you should have pointed to Nazi Germany. There can be little question that the Luftwaffe and the Kriegsmarine had better technology than the Allies, but ultimately Germany lost. I do not think Iran is really in the same position as the Allies were in...
