And this is precisely the reason we need to be able to control our borders and stop the free flow of any Tom, Dick or Abdul. Unfortunately the world is changing and becoming a more dangerous place. Allowing people in who intend to cause us and harm was the objective - the unfortunate thing is that we had to leave the EU to get be able to get this.
Short term pain for long term gain!
I *hope* this is beneficial for all involved, or at least not seriously damaging, but I sincerely doubt it. Honestly I think Brexit has made the world a far more dangerous place than many admit. I wonder how long it will be before Putin's little green men start agitating among countries of the EU to break the EU up. After that, they'll try to instigate hostilities among the old European rivals (UK, France, German, Spain, Italy, etc.), and then swoop into NATO allies in Eastern Europe. At that point we'll be faced with a choice. I guess we'll see how this plays out.
