Kerry Says U.S. Commitment to NATO 'Unwavering' despite Trump

The U.S. commitment to NATO will remain "unwavering" despite the change of administration following the election of Donald Trump as president, outgoing U.S. Secretary of State John Kerry said Tuesday.

"The change of the administration will not change the unwavering commitment of the U.S. to... our NATO obligations," Kerry said after talks with his NATO counterparts in Brussels.

"The U.S. commitment to NATO and Article Five transcends politics," added Kerry, referring to the military alliance's collective defense policy in which an attack on one member is an attack on all.

Trump stoked concerns that Washington's near 70-year European defense guarantee might no longer hold when he said on the campaign trail he would think twice about helping NATO allies who did not pay their defense dues.

His commitments particularly alarmed eastern European NATO countries that are on edge about a more assertive Moscow following Russia's annexation of Crimea and involvement in the conflict in Ukraine.

But Kerry insisted that both the Trump administration and the U.S. Congress would continue to back NATO.

"I'm absolutely confident that the next administration and Congress will stand together," Kerry said in his swansong to Europe.

"I am confident Article Five is not going to be held hostage to the lack of one country or other (to meet its defense spending commitments) ... Article Five is much larger, it is about principle."

The top U.S. diplomat also gave his backing to Trump's pick for defense secretary, retired general James "Mad Dog" Mattis.

"I am confident in some of the people I have seen so far, General Mattis ... I am certain they will remain committed to the core components of the transatlantic alliance," Kerry said.

But he insisted he had no idea of his likely successor as secretary of state.

"The list of people replacing me is growing," Kerry said, with names bandied about for weeks including former Trump critic Mitt Romney, one-time CIA director David Petraeus, former New York mayor Rudy Giuliani, Senate Foreign Relations Chairman Bob Corker or even former U.N. ambassador John Bolton.

Kerry meanwhile insisted that the historic nuclear deal with Iran, which Trump promised during his campaign to tear up, was worth keeping.

"The Iran nuclear agreement has made the world safer," he said.

Overall Kerry said that the world should wait to see what Trump actually does and "must not get all churned up over things that have not happened or appointments that have not been named."

"Common sense will prevail," he added.
