President Donald Trump on Wednesday reversed his position on the North Atlantic Treaty Organization after repeatedly criticizing it on the campaign trail.

They made a change and now they do fight terrorism. I said it was obsolete. Its no longer obsolete, Trump said during a joint press conference at the White House with NATO Secretary General Jens Stoltenberg.

Last year, Trump called NATO obsolete and faulted members of the alliance for not paying their fair share. At one point during the campaign, he even said he would certainly look at pulling the U.S. out of the organization.

This week, however, Trump actually took steps to expand the historic alliance. His administration announced its support for admitting the country of Montenegro into NATO, two weeks after the Senate approved the move.

During his press conference on Wednesday, Trump spoke glowingly of the alliances long history, but again called on NATO members to pay their fair share instead of relying on the United States to make up the difference.

Many have not been doing that, he said. Well be talking about that.

Trump did not, however, offer any bellicose demands or ultimatums as he did on the campaign trail.

NATO is not the only issue Trump sees differently now that he is president. On Wednesday, the Trump administration also reversed itself on the Export/Import Bank , Federal Reserve President Janet Yellen and Chinas currency manipulation .

On Tuesday, Trump also criticized his predecessor Barack Obama for not intervening in Syria in 2013, even though Trump opposed it at the time .
