The blockade of Calais.
Life is full of inconsistencies; the French blockade of Calais proves this better than anything I can think of at the time.
They are blockading the port because of Brexit, having traveled across the EU I can tell you that the blockade is as useless as trying to drain a bathtub using a syringe.
This action shows both the arrogance and the stupidity of the French; while it is it true that the Dover to Calais route is the quickest route into the EU, it is by no means the only route.
For a few miles more on the journey, you can go from Harwich to the Hook of Holland at Rotterdam, and I am sure the only country in the EU I would call an ally for the UK would enjoy the extra income.
My first impression of the Hook of Holland is that it is a thriving port, my first impression of Calais is my Lord, did the war end last week!
Holland is the best country to enter if you wish to go to Germany and the industrial Northern European countries.
Blockading Calais will only harm the French economy, another bonus for the UK is that while they are stopping us getting in, they are also making harder for illegals to come over here; win-win for the UK.
