Hard borders have basically never existed! Do you think the US border to Canada is "hard"? LOL anyone can walk over that and DO! The only times in recent "post ww2" history in Europe, where we have had "hard borders", is with East Germany and the Iron Curtain, and that was the other side making it hard. All we did was put up some barb wire and called that the border... they had guards and mine fields to keep people in.. that was a HARD border.
