I edited to make my post more clear - the OP editorialized the counterattack. The difference today is that Saudi Arabia, Israel, and other smaller nations universally despite Iran and their saber rattling bullshit. It's one thing the majority of the ME can agree on. If there was a war, this one would be short and sweet. The situation 20 years ago was far more muddied and way less agreed on. There are far too many nation state actors that hate Iran to let this one go for long (if indeed all the paranoid tin-foil hat wearing people are right).
