I understand that you stick to the facts and to what might appear to be the most elementary logic, but I will allow myself to say something that you probably could not say yourself: We know in particular that the current occupant of the White House has set himself apart by behaviour that might appear unpredictable, tosay the least, since the beginning of his term. Some people claim that the decision to close the borders completely to flights from all European countries except the United Kingdom is consistent with this type of behaviour, which is unexpected, to say the least. Let's put it that way.
