You could make the same argument about China. Why shouldn't they just agree to no longer be subsidized in exchange for keeping the US in the trade agreement?
Either the price different isn't a huge deal, and China should just pay the cost of the shipments, or the price is a big enough deal that China finds this extremely unfavorable, and "the US should just keep doing it because it's not a big deal" no longer applies.
That's true, but this is a discussion about what the US should do to protect US interests, not about what China should do to protect Chinese interests.
This is exactly the childish "well they started it!" attitude I'm talking about. China is not going to look out for US interests, nor even should they. The US has to look out for US interests, and the US needs to do that by weighing our options and choosing the ones that make sense, not by blaming China and trying to exact petty vengeance.
I don't know what the right thing to do here is, but the only way one possibly could know the right thing to do is by comparing the costs of our options, and there's a complete lack of information on this thread about what the costs of leaving the global postal union are. If you don't know what those costs are, you aren't informed enough to have an opinion on whether we should leave, period. And whining about what other countries do should have no place in deciding what we do.
Have some pride for god's sake, take responsibility for your own choices and stop blaming other people.
I haven't even made a firm argument yet. I'm trying to find out what's actually in the balance so I can make an informed decision.
It may well be that there's no major downside for the US, or for anyone except China. If you can show me evidence of that, I'd love to see it! But this administration has a history of rash, unconsidered actions based on nothing more than pride, so I don't think it's unreasonable to want to see that evidence before I take them at their word.
