LOL. I'm sorry, but your comment makes no sense at all. Trump said that he would respond to any attack disproportionately and immediately.
Quote "targeted 52 Iranian sites (representing the 52 American hostages taken by Iran many years ago), some at a very high level & important to Iran & the Iranian culture, and those targets, and Iran itself, WILL BE HIT VERY FAST AND VERY HARD. The USA wants no more threats!"
What part of VERY FAST and VERY HARD do you have trouble understanding? Are you saying that firing missiles at a country's military base is not considered a threat?! LOL
In any case, this attack has achieved its mission because it humiliated Trump. If it humiliates Trump without a US response, then it's not only a successful attack, but it's purely genius. Trump is the loser of this scenario.
And your analysis does not make sense either. Iran lost one man in an attack that was widely criticized even by Americans. He was replaced in few hours by another general and our proxies are still there in the region. The US will lose its credibility if it doesn't respond to this attack. The US boasts about her super power status. Not to mention that damage to US bases won't be fixed in few hours.
