Nobody wants to invade the UK, neoliberalism has already sent everything worth taking elsewhere.

What the UK needs more than anything is to decouple from the anglo world empire. Y'all have the technology and the population to have a high tech economy and a high standard of living, but as long as America treats Great Britain as an aircraft carrier you don't have the sovereignty to actually fix the problems that were brought on by Thatcher, Blair, et al. I'm not even talking about full communism here (although that would be what I support if I were British), I'm just talking about creating a social democracy powered by a bit of redistribution, pulling money out of opaque financial instruments and investing in actually making things that the world needs.

Now that said I don't necessarily think the UK should give up its nukes, they're an unfortunate necessity in the world we live in, but the Greens are the only ones offering a coherent vision of economic and political realignment. It isn't enough - social democracy isn't enough - but it's a start.
