You think THIS proves the US is not a trustworthy nation? Why choose to ignore the last 100+ years of the US's backstory and focus on this rather minor setback to make such a bold statement? I would imagine any amount of trust we had left was entirely exhausted more than 40 years ago, during the Nixon shock [0] and Exorbitant privilege [1].
Surely, you realize the US earns its status on the global stage via its violent & powerful military, and the PetroDollar? It is foolish to suggest that the US expects other nations to possess any pretense of trust.
You don't have to believe me, because after all I'm just some dumb American. But you may want to take a good look in the mirror and ask yourself who is being the true "American" here.
