France's president warned fellow European countries on Thursday that NATO was dying, citing a lack of coordination and U.S. unpredictability under President Donald Trump, comments quickly rejected as "drastic" by the German chancellor. 

In an interview with British weekly The Economist, Emmanuel Macron expressed doubt about U.S.-led NATO's security maxim that an attack on one ally is an attack on all, which has underpinned transatlantic ties since 1949, when the alliance was founded.

"What we are currently experiencing is the brain death of NATO," Macron said. Asked whether he still believed in the Article Five collective defense guarantee of NATO's treaty, Macron answered, "I don't know," although he said the United States would remain an ally.

Macron has said there is a lack of strategic coordination between European allies on the one hand and the United States and Turkey, with NATO's second largest military on the other.

While France has traditionally had an ambivalent role in NATO, taking no part in its strategic military planning from 1966 to 2009 despite being a founding member, Macron's comments – a month before NATO's December 4 summit in London – were unexpected.

German Chancellor Angela Merkel said he was overreacting.

"The French president has found rather drastic words to express his views. This is not how I see the state of cooperation at NATO," she told a news conference in Berlin alongside NATO Secretary-General Jens Stoltenberg.

In Russia, Macron's comments were hailed as an accurate depiction of NATO's state.

"Golden words … an exact definition of the current state of NATO," Maria Zakharova, the spokeswoman of Russia's Ministry of Foreign Affairs, wrote on her Facebook page.

Foreign Minister Sergey Lavrov on Friday said his country is still interested in building ties with the U.S.-led bloc, but when it gets back on track, "once NATO 'recovers,' we'll be right there."
