Okay, lets say you are correct. You appear to be.
Are you saying we should celebrate because we lost sovereignty and self-determination only 45% of the time?
I wouldn’t sign on to a plan that saw us lose 1% of our sovereignty on any issue.
That's a good question, and I'm afraid you'll see my answer as a dodge. (So let's leave my answer as is, and consider your point taken).
The U.S. freely entered into the agreement that included (and specified) the WTO dispute-resolution process. On that basis (and I see no reason to celebrate it one way or the other) the result is self-determined.
