> the idea of economic destruction akin to what the UK has suffered abhorrent to you?

Yes. But I don’t think Brexit is comparable to what is being proposed here.

In Brexit, the UK invoked Article 50. In this case, the EU would have to execute its Guillotine clause. That dramatically changes the framework for and thus possibility of renegotiations.

There’s not going to be negotiations to drop the core principles, I don’t know why bunch of people keep imagining this. UK was let go, Switzerland will be let go too.

Hoping different outcome by negotiation over this is like hoping for negotiating your way out of your gym membership payment when still attending. Not going to happen unless you become a charity case or insignificant, being significant is not a strength its a weakness when you are looking for charity or special treatment. Switzerland can imagine being too important to loose just as UK thought and they will be let go as UK.

I guess leaving EU can be useful to those who want to do things to Switzerland just like they did things to UK.
