I know most of us here would like to see the US tell the UN to take a hike, which will probably never happen. Given the numbers in the linked article though, I don't know why we have never just told them, "we're cutting our payments by 25%. Deal with it."
While I wouldn't expect it from this administration, it should have happened in several past administrations. Seriously, what would the UN do except roll over? They can't tell us to leave, because they need us about 100,000 times more than we need them. Either countries that have been getting a free ride would have to step up, or not, because who (in the US) cares if they don't? The UN knows they can keep giving them (including big dogs like China and Russia) a free ride because we're the ones who always roll over.
I really hope the next Republican administration puts its foot down about this.
