Since his first administration, President Donald Trump has stressed the need for U.S. allies to take on more of the burden to offset what he has said are decades of them taking advantage of the United States.

U.S. Defense Secretary Pete Hegseth said that many countries appeared to be on track to agree to spending 5% of gross domestic product on their security needs.

NATO countries are using creative math to meet the U.S. president’s demand to more than double annual spending, partly by expanding what counts beyond soldiers and weapons.
