Sure. But, I mean, look at some of the points they try to make. The situation in Syria is supposedly evidence of the decline of US power. No, Syria is evidence of the US public's unwillingness to contribute more American blood to a foreign war. We spent the last century dying in various jungles and deserts without much to show for it. It simply illustrates that foreign military power, in many conflicts, accomplishes very little. We could be MORE powerful, that fact still wouldn't change.
The stupidest part of the article, though, was part about young Americans not thinking the US is great. Uh, newsflash: the suggestion that the US is objectively the greatest country in every way has always been absurd. The fact that young Americans now realize this isn't indicative of anything. Again, we could be getting MORE powerful and MORE influential, it still wouldn't affect the absurdity of that statement.
