Normally this would have been the end of it, lessons would be learned, and strategic directions adjusted. Instead the game was reset and the Iranian side was handicapped to prevent them from doing various things, effectively imposing a scripted result. This led to the US winning by an overwhelming margin and somehow the results of this rigged game were used to align strategic initiatives moving forward.
In modern times we increasingly seem to have entered into an era where people are willing to believe what they want to believe, rather than what they know to be true. And while it's easy to mock politicians and the military for this, this is also a mainstay of contemporary political discourse among regular people, including those who fancy themselves as well educated, on a variety of controversial issues.
I don't know what started this trend, but it should die. At least in terms of war it's self correcting. The US can't handle many more botched invasions or interventions, and I suspect we're already beyond the point of no return in terms of consequences of these errors.
