We also have to recognize that these particular narratives actually created some objectively positive accomplishments as well. That's what made the postwar US different than the postwar USSR. We can plainly see the results in some pretty well set up experiments (eg East Germany vs West Germany). It's very easy to criticize the failings of liberal American values and liberties looking from a vantage point where we get to take those values and liberties for granted.

... but now it seems as if people got bored of those lofty narratives, and the US can't even prevent its own domestic jihadis from overrunning the country with backwards fundamentalism. So now we're staring down their equivalent of Sharia law while they rally around regime-sponsored murderers ramping up sectarian violence.
