The EU is perfectly willing to have a trade deal with the UK, but if the UK wants something like Norway or Switzerland has, then it needs to allow freedom of goods, services, capital and EU citizens. If they want something else then they need to negotiate the terms just like anybody else
The UK under WTO terms will be just like everybody else. They will not "do fine" - but they won't collapse economically yet. They will have a hit of anything from 2% to 4% GDP in the 2 year horizon. After that, it all depends on how well their government manages it
But that's the crux - May has NOT managed anything so far, so expecting her to manage the no-deal Brexit is a larf
Two thirds of current trade is with the EU. Those percentages were radically different before Britain joined the EU and could well shift back to other markets once Britain leaves. Its not like Britain was a poor country prior to joining the then European Community. I agree that May has done nothing except roll over or Brussels and try to ram down the throats of the British people a worse arrangement than they had before Brexit. That failed. Britain obviously needs to move in a different direction. I agree that a bridge will be needed to buy Britain a little time to negotiate new trade arrangements. I'd like to see the US offer them a deal to do just that.
