Unfortunately, I have absolutely no confidence in this SC upholding America against the president. Some have been bought and paid for years in advance of this situation. Some, like many in the congress, are afraid for the lives of themselves and their families. Americans on both sides are watching and waiting to see what happens if the president actually ignores the court. If he does, and congress does not step in, I think our republic may be doomed. It has happened before in other places, it can happen here.
If nuclear missiles start flying it won't matter whether we have a golden dome or not. It will officially be the end of the world as we know it. If someone is shooting missiles at us, we will be shooting back at them. And don't forget, a nuclear explosion even in the atmosphere is going to screw up basic infrastructure like electricity and phones. Armageddon will have begun.
