US will lose world power by 2020 - professor sociology Norway

With the election of Trump, a professor Galtung  in Norway who has modeled how other Empires have fallen, predicted:

Galtung’s biographer credits the sociologist and mathematician with correctly predicting the 1978 Iranian revolution; China’s Tiananmen Square uprising in 1989; the collapse of the Soviet empire in 1989; the economic crises of 1987, 2008 and 2011; and the 9/11 attacks.. Raw Story

He's not talking about a bit of a collapse here and there either, but such a collapse as to affect borders and politics across the world of the same magnitude as the collapse of the Soviet Union last century.

 Rising tensions between America’s Judeo-Christian majority and Islam and other religious minorities created cultural contradictions, which are further sharpened by social contradictions between the so-called American dream and the reality that fewer Americans can achieve prosperity through hard work. 

The decline of the U.S. as a global power would probably rip apart its domestic cohesion, Galtung said, which could potentially reshape American borders. 

“As a trans-border structure the collapse I am thinking of is global, not domestic,” Galtung said. “But it may have domestic repercussion, like white supremacists or even minorities like Hawaiians, Inuits, indigenous Americans and black Americans doing the same, maybe arguing for the United States as community, confederation rather than a ‘union.'” Raw Story

My first reaction after seeing Trump win was "It's the end of Empire". I see no reason to change that view, and that in fact it's been happening for some time now.

Albeit the soon to be Emperor has no clothes, ugh..... 

In hindsight I put the beginning of the end down to the humiliation of Vietnam, followed by just a few years later the election of Reaganomic trickle down as the god of society and the market. A nonsensical ideology that redistributed wealth out of the common man and gave it to a very few at the top.
