Reexamining past narratives/theories based on new data or ways of viewing things is the core of science. It's particularly important in softer social sciences where so much of the effects can only be viewed in the long term.

My point is you can't go back to there, at least not without another massive war and this time the chances the US gets by unscathed is practically zero.
Not to mention shattering the alliances that put the US in that position isn't the way to get back there either. Even if we tried countries are going to be a lot more wary of trusting the US for critical things like military protection which was a major part of the deal for the US's position, we extend a military umbrella across your country and we get good access to your markets.
Trump et al fundamentally misunderstand why we were in the position we were and their actions push us further away rather than bringing us back to it.

Or even inside the US itself.
The combination of state, industry and WMF-type loans extended American power globally. It was a very very good time to be American. This is the core of the "Great Again" part of the slogan. Boomers remember this America and want the growth, wealth and dominance back.
