Germany is in for a 'rough ride' says its vice chancellor
The country's vice chancellor has also said he will look towards Asia as he fears the breakdown of relations between the two nations.
In an unusual attack, Sigmar Gabriel of the Social Democratic Party of Germany, signalled the country is preparing for a bleak future.
And he claimed Donald Trump's inauguration speech was “nationalistic”.
He told public service broadcaster ZDF: "What we heard today were high nationalistic tones.

"I think we have to prepare for a rough ride."
The comments come after President Trump previously stated he plans to scrap the controversial TTIP trade deal between America and Europe.
It also comes after it was revealed outgoing President Barack Obama picked up the phone Angela Merkel in his last call as leader.
According to reports Obama thanked Merkel for her friendship and praised her for her role in world politics during his period in office.
Donald Trump seemed pensive today before he was sworn in
A statement from The White House said: "The President thanked Chancellor Merkel for her strong, courageous, and steady leadership.
“Given their eight years of friendship and partnership, the President noted that it was fitting that his final call with a foreign leader was with Chancellor Merkel, and he wished her the very best going forward.”
Merkel is up for re-election next year and is hoping to keep her position as Chancellor.
Unlike Obama, Trump has openly criticised Merkel.

He said that Merkel made a “catastrophic mistake” by taking in hundreds of thousands of refugees from Syria and the Middle East.
The Obamas told Angela Merkel they had appreciated their personal friendship and forging a deeper partnership between Berlin and Washington.
Earlier this week Mr Trump took aim at Mrs Merkel, saying: "I think she made one very catastrophic mistake and that was taking all of these illegals, you know taking all of the people from wherever they come from. And nobody even knows where they come from.
"You look at the European Union and it's Germany. Basically a vehicle for Germany. That's why I thought the UK was so smart in getting out."
Mr Trump also appears to have reservations about NATO which has caused concerns in Europe.

He said: "I said a long time ago — that NATO had problems.
"Number one it was obsolete, because it was, you know, designed many, many years ago. Number two — the countries aren't paying what they're supposed to pay.
"I took such heat, when I said NATO was obsolete.

"It's obsolete because it wasn't taking care of terror. I took a lot of heat for two days.
"And the other thing is the countries aren't paying their fair share so we're supposed to protect countries but a lot of these countries aren't paying what they're supposed to be paying, which I think is very unfair to the United States.
"With that being said, NATO is very important to me.
"There's five countries that are paying what they're supposed to. Five. It's not much, from 22."
