Correct me if I’m wrong but I think an issue with that is that there isn’t a mechanism for kicking a country out; the US would have to choose to leave. So more likely the allied nations would have to reform a new agreement which has its own red tape.

Maybe I’m wrong but I’m interpreting this being in the vein of a crime being murder, but potentially also a hate crime. The motivation of a crime is part of its definition and affects sentencing especially in tertiary cases eg attempted murder, manslaughter etc.
