It ultimately depends on whether you’re looking from the perspectives of those during that time, or from a modern perspective with the benefit of hindsight and better objectivity.

The key it all kinda hinges around is that they did not know the communist project of the USSR was going to eventually implode in pretty much every place it was attempted. Had they known that, it is likely we would have been in fewer wars.

Ultimately though, it is difficult to legitimately argue that the US, with its gargantuan economy, first-rate military, nuclear arsenal, boundless soft power exports and two oceans to defend it, has ever been legitimately threatened with potential defeat since WW2. And even including WW2 is ultimately debatable, simply due to oceans being an extremely effective defense from invasion.
