Hungarian Prime Minister Viktor Orbán called on EU countries to adapt U.S. President Donald Trump's slogan and "make Europe great again" — but he wasn't talking about the European Union.

Orbán, speaking on Thursday at the Brussels offices of the Konrad Adenauer Stiftung, the political foundation close to Chancellor Angela Merkel's Christian Democrats, said Europe should adapt to the new world order rather than denying it exists.

"There is a saying: whatever exists is possible," Orbán said, adding this was his "number one principle in political leadership." But he said many in Europe would ignore the "new paradigm" of a world with "multiple centers of power." He listed the U.S., China, and Russia but not the EU.

Orbán called on fellow EU leaders to acknowledge that the bloc faces multiple crises — weak economic growth, aging societies, poor foreign policy choices and a lack of trust among the electorate — and forecast the EU's decline from being a "regional power" today to having even less influence.

His recipe to reverse the decline? Leaders should get rid of "a utopia called supranational Europe." If Europe wanted to become competitive again, it "must abandon the illusion of federalism," Orbán said. "We're interested in a strong Hungary in a strong Europe."

"Europe was never strong when it was directed from one strong center, but when there were multiple centers," Orbán said.

"Europe itself must become multipolar," Orbán said, and seek a new relationship with the United States "instead of the doomed free trade agreement," must deal with China and "place the issue of Russia back on the agenda."

"In my opinion, a nation or a community that is unable to reproduce itself does not deserve to exist ... This problem and this crisis cannot be solved or treated with migration, with migrants, with guest workers, or with common tricks."

Such a "community does not believe in its own future, and therefore there is no place for it in the future."
