Probably should not post here, but I will anyway. This is a weary, globally connected, overcrowded world we live in these days. The objective reality is that, at present, the USA is the most powerful among world governments and countries, but no country or power has the influence and control they had 70, 50 or even 30 years ago.

Any perspectives, domestic or foreign, that cling to the notion the USA can either save the world or will be the demise of the world are not realistic.

Also a mistake to overestimate the power of the Presidency in this post modern world. Not saying it is not still a powerful position.
