This is quite an ignorant and dangerous opinion. Unfortunately you are not the only person to hold it.
You are quite entitled to your opinion and I respect it. Pity you can not extend the same courtesy.
The W in WTO means world as in the "free" world. The E in EU means parts of European bureaucracy that applies a "you shall obey" doctrine. Which is larger?
But of course, the remoaners will whinge on about how every other nation in the world is out to screw us while lovely little fluffy France and Germany only want to be our besties.
The EU is typically returning the usual intransigence with Juncker's "the withdrawal agreement will not be re-opened" speech. Like Shotshy, I am happy for us to reply on the lines of "in that case, Unidentified Flying Object".
One prediction I would have if there is no deal and tariffs are introduced, THAT is when you will start to see action from the companies that currently export heavily to the UK to pursue a quick free trade deal. They have no reason to raise their heads until no deal becomes reality.
Also, all the doom stories about Dover will then apply to Calais as well. Of course, at the moment Macron only has to deal with his 20% approval rate, Paris Riots, having to order a national increase in wages, and pissing off Trump so he is probably looking for something else to occupy himself.
What a thriving little continent it will be without us and our useless contributions ! - no wonder Juncker can be so dismissive.
