Sorry for being nosy.
It has more to do with your assessment that the United States would honor its treaty obligations under the Washington Treaty. I'd ask what evidence you have for that conclusion.
Trump has this weird ability to get his domestic opponents to come to the
strangest conclusions.
If you are a Trump voter and you believe it would be 50/50 whether the US would honor Article V of the Washington Treaty, then I'd ask why you voted for him.
If you are a Biden-Harris voter, then I would chalk your assessment up to partisan thinking.
