Correct, it is a spending goal, not a requirement. Or at most a soft requirement. Still, my point still stands, every NATO member on the "frontier" with Russia is meeting or exceeding that 2% goal. They are pulling their own weight. At least from what I recall, the three Baltic nations and Poland are all above the 2% GDP target, and I believe Finland, Romania, and Hungary are or will be as well.

The US and Trumps criticism of "freeloaders" could be seen to apply, but to the countries that aren't anywhere near the frontlines. I think Luxembourg is less than 1% GDP of spending on military, and Canada is around 1.5%. Trumps criticism, if interpreted generously could be taken to mean that the US wouldn't help Belgium, but if Belgium is invaded, there's something big going wrong.

Realistically, Trump's weak assertions would seem to signal that he doesn't care if Latvia is pulling its weight, because it's a small country and small countries deserve to be get eaten by bigger countries. This uncertainty is what would seem to have rattled European NATO countries and reignited the effort for a collective EU defence framework.

The other thing that bugs me with Americans whinging about "NATO freeloaders" is that Article 5, the collective defence clause, has been invoked once in the entire history of NATO. By the US after 9/11. And everyone stepped up. The US can complain about Canada's military spending, but Canadian soldiers that were fighting and dying alongside the Americans in Afghanistan. It's a bit rich coming from Trump, bone-spurs himself, that other NATO countries aren't pulling their own weight.
