All but 5 countries are within spitting distance, and none of them spend significantly less than the US in terms of precentage. Only 3.16 of our GDP, with most nations averaging around 1.5 - 1.2% of their GDP, with the top spenders that are under 2% being 1.78, 1.56, 1.54, 1.49, and 1.38. Many of these nations produce such low GDP that even if they upped their contributions to above 2% it’d be a drop in the bucket. The only straggler that has no excuse is Canada, but they make up for it by fielding a large bulk of the peace keeper forces. Ultimately, the US, the Uk, and Germany are going to shoulder a bulk of the fiscal end of NATO. We also have the largest armed forces out of every NATO member. Logically speaking, we’re going to be the center pole.
Trumps secretary of state pick has even said there is little way that most NATO allies could reach the 2% goal, so the spending is going to be skewed.
However, my issue is with Trumps comments on NATO being obsolete, which is disconcerting.
