There were already many areas that we were failing in before Bush. While he will likely be remembered as the most feckless President in our history, there are many architects to the decline of the US, if you bother to read the article.
Thus far, Trajan has made the only reply based on reading it.
Personally, I have no opinion as to whether we will see a rapid decline near the date stated. But the reasons stated are valid.
Taking down America: four scenarios for the end of the American Century by 2025 | Energy Bulletin
By 2008, the United States had already fallen to number three in global merchandise exports, with just 11% of them compared to 12% for China and 16% for the European Union. There is no reason to believe that this trend will reverse itself.
Similarly, American leadership in technological innovation is on the wane. In 2008, the U.S. was still number two behind Japan in worldwide patent applications with 232,000, but China was closing fast at 195,000, thanks to a blistering 400% increase since 2000. A harbinger of further decline: in 2009 the U.S. hit rock bottom in ranking among the 40 nations surveyed by the Information Technology & Innovation Foundation when it came to change in global innovation-based competitiveness during the previous decade. Adding substance to these statistics, in October China's Defense Ministry unveiled the world's fastest supercomputer, the Tianhe-1A, so powerful, said one U.S. expert, that it blows away the existing No. 1 machine in America.
Add to this clear evidence that the U.S. education system, that source of future scientists and innovators, has been falling behind its competitors. After leading the world for decades in 25- to 34-year-olds with university degrees, the country sank to 12th place in 2010. The World Economic Forum ranked the United States at a mediocre 52nd among 139 nations in the quality of its university math and science instruction in 2010. Nearly half of all graduate students in the sciences in the U.S. are now foreigners, most of whom will be heading home, not staying here as once would have happened. By 2025, in other words, the United States is likely to face a critical shortage of talented scientists.
