As for enemies, we've had many more terrorist attacks in the UK than the whole of the US.
I don't know why it seems that people who settle in USA, adopt it as `their country' and are forever singing the praises of 'Uncle Sam.'
Whereas, people often settle in UK but still fail to become British in their minds, and many cannot wait to leave on their retirement and return to their 'home county' with very little good to say about the country which made their future possible.
My mother was from Northern Ireland, my ex wife from Eire. Both lived practically their whole lives in England but neither of them, nor other members of their families, ever thought of them as anything but Irish and ran down England at every opportunity.
