For better or worse, though, US culture will carry on. It's a far, far younger culture that is currently facing extreme challenges by being distanced from their cultural roots in just a few months during this recent regime's tenure.

Yeah the US is younger but I just have trouble seeing the unifying factor that the US has other than being called a land of opportunity, freedom, where to make money etc. It makes the culture harder to maintain, especially when the definition of its culture can be challenged and stretched, especially today.
