Fox has been out of office for ten years, and the current president actually invited Trump to Mexico where he, at least publicly, let Trump walk all over him and could not have possibly looked weaker or more inept. That might not actually mean anything substantive, but when it all comes down to it, to paraphrase Walter Sobchak, the wall is not the issue here. The issue is that we're strong, they're weak, and we can say the vilest things about them until the end of time and still force them to do what we want them to do. That fact has not changed, wall or no wall.
