Man who predicted 911 attack and fall of Berlin Wall, has the worst prediction for America under Trump.

Johan Galtung, a sociologist credited with predicting the fall of the Soviet Union has warned that US global power is in a phase of accelerated decline under the leadership of Donald Trump

The Norwegian professor says America will collapse while the property mogul is the White House.

Galtung is known as the "founding father" of peace studies as a scientific subject and is recognised for correctly predicting numerous historical events, among them the Tiananmen Square uprising in China and the September 11 attacks.

According to Independent, he attracted controversy in 2000 when he predicted US global power would collapse by 2025.

But under the Bush administration he revised his forecast for the collapse to 2020. Now, he says that reality that is materialising following election of the bombastic billionaire.

Trump’s election on an anti-immigrant platform coincides with one of the final phases of the decline predicted in the social scientist’s 2009 book The Fall of the American Empire—and then What? where he forecast the rise of facism before the country's power receded.

The President-elect has vowed to deport three million illegal immigrants as soon as he enters office and build a wall along the American border with Mexico.

He told Motherboard the election of Mr Trump "speeds up the decline", although he qualified the statement, saying: "Of course, what he does as a President remains to be seen."

Dr Galtung added that the President-elect's critical attitude to Nato also indicated the US would cease to be a superpower.

The Republican has previously indicated the US might not come to the aid of those in the alliance if they failed to meet the designated defence spending.

“The collapse has two faces,” Dr Galtung told the tech news site, “Other countries refuse to be good allies and the USA has to do the killing themselves, by bombing from high altitudes, drones steered by computer from an office, special forces killing all over the place.

"Both are happening today, except for Northern Europe, which supports these wars, for now. That will probably not continue beyond 2020, so I stand by that deadline.”

Yet Xenia Wickett, head of the US and Americas programme at think-tank Chatham House told The Independent it was "totally unrealistic" to believe the US would stop being a global power by 2020.

"The US is a global power for many reasons. It has the strongest military in the world, it has the most robust soft power in terms of its universities, [...] in terms of its companies and in terms of the reach of its media. It also remains the biggest economy in the world. The idea that any of these things are going to change in the next four years is unrealistic."

Meanwhile, Donald Trump’s incoming White House press secretary Sean Spicer is whining that Trump is not getting the respect that he deserves.

It is clear that the president-elect and his team are very upset about a perceived lack of respect from the media and the American people.

In an interview with the Hill, Spicer moaned about Trump not getting the respect that he deserves from the press, “There’s some positive aspects here and there, but largely it still continues to not treat him with the respect that he deserves.

I think for a lot of folks inside the beltway, and inside pundit-world, they don’t fully appreciate the understanding that he has of where the American people are.

They continue to mock him in ways, when it frankly just shows the lack of understanding of that they have of where the American people are and what they think.”

Spicer’s latest comments come one week after he complained to ABC’s This Week about Trump being mocked, “Everything he does right now, he gets — he speaks for the head of Sprint, gets 5,000 jobs moved from abroad. And everyone starts to mock him. Oh, those jobs were already announced.

They weren’t. The sales jobs have been a previous announce. These jobs were coming from abroad to America. And instead of trying to mock him or undermine him, it’s time that people started to give him credit for actually getting things done.”

There has been very little mocking of Trump in the media. In terms of television, the bulk of the coverage has been soft on the president-elect.
