President Donald Trump is considering changing U.S. engagement with NATO to favor members who spend a set percentage of their GDP on defense, NBC News reports.
Officials told the network that under the changed policy, the U.S. might not come to the aid of a NATO member that has been attacked if they don’t spend a certain amount of their GDP (Gross Domestic Product) on defense. The change would be a departure from NATO’s Article 5, which states that an attack on one country is an attack on all.
