If as you keep telling us there is no real support for brexit amongst the people and it is such an unpopular course of action only wanted by a handful of uneducated and ill informed sheep why would the tories be willing to piss the country and their party up the wall (according to you) for fear of UKIP? You say it would cause a resurgent UKIP, how would that happen in your world of the europe loving population?
I said very little of what you suggest. Two years ago, few woters cared very much about UK membership of the EU. They have only come to a decision because the issue was forced by UKIP and Farage. The essential plan to encourage people to vote leave has been much the same as UK governments have used over the years: blame the EU for everything which has gone wrong. A lot has gone wrong and it is squarely the fault of Uk governments, world governments in particular US foreign intervention, international conflict both military and economic, and very little is to do with the EU. UKIP succeeded in harnessing a feeling of dissatisfaction and falling relative wealth in a protest vote against the staus quo, expressed as EU membership.
Faced with this, the conservatives could either have opposed it or embraced it. If they opposed it, they would be the establishment opposing the outsider, conservatives pitched against UKIP. They decided to take control of the process of Brexit, rather than hand it over to UKIP to implement. The big idea is hardly novel, it is for the conservatives to stay in power. if you notice over the years they have attacked labour policies, and then quietly adopted them. They proclaim how they have made people richer by steeply increasing the starting point for income tax, which was a liberal policy. If your opponents policies are popular, adopt them.
But equally, this means they will drop Brexit just as quickly if the public turns against it. The problem then would be to justify having adopted it in the first place, and the best way to do that is probably exactly what they have been doing. Stress that they adopted it because of the will of the voters, and because they honestly believed it could work. Then, when it all goes horribly wrong, they can say they did their very best to implement something which they honestly believed was a good course for the country, which voters had asked for, but then eventually had to accept that it was not achievable.
Right now they are trying to spin the EU as to blame for the failure of Brexit. It has not yet even failed, and they are blaming the EU for the failure they are expecting to happen! Fundamentally this is an absurd argument. If the Uk leaves the EU, it must expect its new relations will be on terms similar to other nations currently outside enjoy, and not similar to those nations currently inside enjoy. That ought to be clear to everyone.
What is likely to happen, is that trade will decline slowly, taking account of the new terms. Brits will not stop buying luxury german cars just because they are a bit dearer. Europeans may more readily stop buying budget british cars, because they are no longer budget. More significant will be rules and regulations about how trade is conducted, which in the modern world are more effective at stopping unwanted trade than simple taxes on imports. For example, if the UK decides to drive on the opposite side of the road to the EU, that immediately puts Uk car manufacturers at disadvantage. The Uk will probably continue to enforce and adopt very many trade rules decided by the EU, even if we wholly withdraw from any mutual agreements. because it benefits our exporters to follow the unified rules which apply to all goods used across the EU. leaving will not restore any Uk sovereignty in this respect.
The real danger is that half the UK economy is based on trade with the EU. Much of this presupposes that the EU is a member with free trading access to all the countries. That is why the Uk has a car industry, because companies like Nissan needed a base inside the EU. Similarly, the financial city of London has grown hugely, trading into Europe. This draw to the Uk will go into reverse if we leave the EU. It isnt just that goods made in the Uk will become a bit more expensive in the Eu, it is that the manufacturers of those goods will move their operations to another EU country, and then the Uk will lose the entire operation. Both the parts selling into the EU, and the parts selling to the rest of the world.
The government, somewhat desperate I fancy, is currently latching onto trump as their saviour. A person many government ministers reviled when they thought he could never win. Trump has stated very very clearly his policy is 'America first'. His aim is to bring car manufacturers back into the US. Banks back into the US. Sell the UK US farm produce, raised to much lower US safety and animal wlefare standards. Get the UK to pay full price for expensive US drugs for the NHS. Yes, Trump would love a trade deal with the Uk to achieve all these things the US could not achieve in deals with the EU.
The government understands that in order to retain popular support, it has to wait until brexit fails before it changes course and stops it. The problem is that by this time, irreperable damage will have been done to the Uk economy. It has already started.
