Re: "SEE YOU IN COURT, THE SECURITY OF OUR NATION IS AT STAKE!"
I disagree. He promised he'd keep 'America safe'. If a terrorist attack happens now, no matter what the reason, he'll have failed to keep one of his biggest and boldest campaign promises.
He made the promise, it's up to him to keep it within the bounds of the law and the Constitution of the United States.
Add to the that his wall probably won't even start to be built for several years, he'll be hard pushed to win another term (assuming Congress doesn't see an opportunity to impeach his ass before then, in a shameless attempt to look reasonable to the electorate before the mid-terms).
His popularity is already tanking, and it isn't even a month in and has a major judicial showdown AND and embarrassing military failure under his belt; it's altogether not looking good for the orange buffoon. He was already looking weak and ineffectual and this 3-0 appellate court decision against him makes it even worse and further solidifies the fact you can't rule by EOs and PMs alone.
