It would need to start happening in a country that's in a position of defying the United States, or happening in the United States itself.

So long as the policy is perpetuated by people who are elected by those who still sheltered from the worst of it, I wouldn't expect any change.

Particularly not now that there's a robust military-incarceration-industrial lobby with a strong incentive to maintain the status quo and no limitation on their ability to make 'campaign contributions'.
