Here's who is paying their fair share to NATO - and who isn't

Defense Secretary Jim Mattis reportedly said Wednesday that NATO member countries should start paying more into the alliance or else the US may "moderate" its commitment.

"I owe it to you all to give you clarity on the political reality in the United States, and to state the fair demand from my country's people in concrete terms," Mattis told NATO defense ministers, according to The Washington Post.

Only five of NATO's 28 member countries last year met the alliance goal of spending at least 2 percent of their economy on defense.

"America will meet its responsibilities, but if your nations do not want to see America moderate its commitment to the alliance, each of your capitals needs to show its support for our common defense," Mattis said.
