What does this all mean?

I see a few key patterns here. First, the decision to first block, and then allow, green card holders was meant to create chaos and pull out opposition; they never intended to hold it for too long. It wouldn’t surprise me if the goal is to create “resistance fatigue,” to get Americans to the point where they’re more likely to say “Oh, another protest? Don’t you guys ever stop?” relatively quickly.

However, the conspicuous absence of provisions preventing them from executing any of the “next steps” I outlined yesterday, such as bulk revocation of visas (including green cards) from nationals of various countries, and then pursuing them using mechanisms being set up for Latinos, highlights that this does not mean any sort of backing down on the part of the regime.
Note also the most frightening escalation last night was that the DHS made it fairly clear that they did not feel bound to obey any court orders. CBP continued to deny all access to counsel, detain people, and deport them in direct contravention to the court’s order, citing “upper management,” and the DHS made a formal (but confusing) statement that they would continue to follow the President’s orders. (See my updates from yesterday, and the various links there, for details) Significant in today’s updates is any lack of suggestion that the courts’ authority played a role in the decision.

That is to say, the administration is testing the extent to which the DHS (and other executive agencies) can act and ignore orders from the other branches of government. This is as serious as it can possibly get: all of the arguments about whether order X or Y is unconstitutional mean nothing if elements of the government are executing them and the courts are being ignored.

Yesterday was the trial balloon for a coup d’état against the United States. It gave them useful information.
