Hi Terry, I don't think it is 'written in stone'. If anything, exiting the EU can bifurcate in two +- extremes. Or give a middle road.
In the case of a Brexit:
One extreme is when the conservatives (Tories) win with Mr. Johnson. The country will be sold out, there will be no climate mitigation, a return to the 'values' of colonial aristocracy and establish a Dickensian dystopia. Already they created an evil 'hostile environment', courtesy of Mrs. May.
The other extreme is when The Green Party gets a majority mandate. They will transform the country by undoing most of the evils of Tory policies and radically change society to less inequality, strong human rights and strong mitigation. They are visionary imo. They are far less political than the rest and are not deeply and secretly connected to the old boys. I think Caroline Lucas would be a good leader. More women are needed but not monsters such as Thatcher and May (I might have insulted Mrs. Thatcher here).
Very unlikely this extreme is going to unfold because of too much sanity, first-past-the-post and media attention.
The middle of the road would be Labour and Jeremy Corbyn. I don't trust them. They earlier delivered the horror of Tony Blair. They continued austerity when they were in government. They are not the answer but also not the enemy of the people and are not going to sell out Britain. It will be ELSD, infighting and, in my expectation, steerless and not visionary. Afraid of hard and unpopular decisions.
So in my view Brexit is a great opportunity to free the U.K. from the shackles of the neo-liberalist GPD-focussed EU.
If the The conservatives win it will be a freefall into the deepest hell for most people and living nature.
If The Green Party wins they will start with radical change, which is made a lot easier by being outside of the EU economic regulations.
If Labour wins it will go in a positive direction but there won't be radical change I expect. Too much inertia, conflicting interest and politics.
The Tories want a no-deal Brexit.
Labour has not been outspoken about Brexit. It's unclear to me what they're up too but I don't trust them even though their intentions are good.
I think The Green Party won't get a lot of votes because of 'strategic voting', which means that you don't vote for the party you think is best (The Green Party), but instead vote for another party (Labour) in order to try to stop the Tories and Mr. Johnson from winning.
I am not interested in NATO and have little knowledge about it. I suspect the Tories would bend over to Trump and let the U.K. become a vasal state of the U.S.A.. A powerful ally. Labour would probably stand up but not fully erect. The Green Party will not do the bidding of Mr. Trump and oppose NATO's aggression and might even exit NATO.
Finland is not part of NATO and hasn't got a standing army. And look at their government
