The article says that Trump is moving to pull out of or renegotiate the UPU agreement, which at worst is a Presidential choice, and it's not even clear to me why USPS can't do it unilaterally.
The UN can "force" rules upon us if we sign an agreement allowing them to do so. If we sign a treaty agreeing to abide by the rules set by a UN agency, then they can impose such rules, and under the US Constitution, such rules have the force of law within the US.
The rules might not be fair. Our recourse is to try to change the rules, and failing that, threaten to withdraw from the agreement. That's what we're doing.
They have zero power. The US can destroy the UN in a flash.
But in that instance, humanity would pay much more than extra bucks for shipping crap we don't need.
A strong AND fair UN is a good deterrent for world wars.
Of course, it's better to renegotiate any precieved unfairness than to just blow all violence avoidance safeguards like a world congress.
China got away with their economic trickery because of US corporate greed and short sightedness combined with the US public insatiable consumerism.
But we humans have a short memory and we like being empowered by bully leaders.
Let's just hope we'll survive this age without too much bloodshed.
