Europe

I think she is hopelessly naive if she thinks Britain will have no trouble satisfying the Copenhagen criteria and that it might even get some exceptions from the regular rules for joining the EU again.

I would argue that the UK doesn't have a functioning democracy at the moment, nor does it fulfil many of the criteria that she brushes away with something about being a recent member because the Tories and the ERG in particular have worked to ensure exactly that. Some of the recent non-EU UK trade deals would become a problem as well.

A small minority also won't be enough to convince any EU member state to allow the UK back in, it needs a solid majority that will persist even if the government in the UK changes again.

Negotiations with a country that basically can't be trusted to stick to anything negotiated will also be incredibly difficult compared to your average country.

Britain also doesn't have much to offer considering the EU doesn't have much trouble exporting to the UK while they are not performing any checks. Nor is anyone keen on Britain's obstructionist attitude in the EU processes again.

I would suggest the UK should concentrate on political, media and education reform to have a population with a better idea of their actual place in the world (and how their history is seen elsewhere) and a political system with actual checks and balances that actually represents the population.
