What is NATO's new 5% defence spending target?

BRUSSELS, - NATO leaders are expected to endorse a big new defence spending target at an alliance summit in The Hague on Wednesday, as demanded by U.S. President Donald Trump.

They are expected to agree that NATO members should spend 5% of their economic output - or Gross Domestic Product - on core defence and broader defence and security-related investments.

That’s a hefty increase on the current goal of 2%, which was approved at an alliance summit in Wales in 2014. But the new target will be measured differently.
