> The USA is more likely on a steady course of becoming increasingly less relevant to anyone but themselves. While it is certainly true that the USA is loosing it's status as the world's only superpower, it is still very much the most powerfull country and will probably stay, if not number 1, at least in the top 3 for at least the rest of our lifetime. I wouldn't call that irrelevant.
However, the US has about entirely lost their status as a model. As-is, following US legislation would require some amount of apologetic discourse anywhere outside of North America. (That the US have left the international community for the most, or, at least, have proposed to do so – especially, when it comes to treaties and jurisdiction – doesn't especially help either.)
Now I might be wrong, maybe the isolasionist mentality is more profound than that. An historical argument to show how this is stance is not new is the refusal for the US to enter WWII until Japan basically forced their hand on the issue.
