To an extent, I agree with your last post, John.
This country has far more in common idealogically with the US than with Europe, with which we are geographically linked.
Years back, I seem to recall some rumblings about us becoming the 51st State, but It was firmly stepped on by the Government of the time.
As I see it, the Government could not countenance us joining the US, as it would mean relinquishing our sovereignty to a country that had broken away from our rule and gone their own way. The old 'You beat me up, I'm going to hate you for ever!' syndrome.
Successive British Governments have thought more of protecting Britain's sovereignty from the US, while at the same time we are being subsumed totally by Europe. It won't matter soon which party gets in, as we'll be ruled by the EU, whether we like it or not.
I feel that if we's become the 51st State, at least we'd still be able to keep our own laws and industries. In Europe, they are just bleeding us to death, financially and industrially.
Cheers, HG
