What sort of threat modeling would have prevented this?
There are plenty of mitigation and stonewalling going on, but mostly through the courts.
Executives must have some power, or else the process itself becomes the executive and there's no ability to respond to anything.
If there's anybody to blame, we must place the blame on the executive wielding the power, and those who have enabled this to happen by putting that particular executive in power by subverting the traditional vetting process. If a political party no longer performs basic vetting of that level then the entire party should probably be eliminated.
