Where should I emigrate to?

In the next 10 years I’m looking to leave the UK as it is ‘going to the dogs’. I really wouldn’t want to raise my kids here as I think it is small minded and spineless.
I grew up in Abu Dhabi (UAE) and went to an American international school – which I loved every second of. I want to move somewhere where the weather is nice, it’s not in the middle of nowhere (i.e. close to a big city), low crime rate, people of many nationalities (i.e. – international schools) and it’s no more than 7 hours flight from the UK. HELP!
(We were thinking of North/South Carolina but I have since realised that it may be missing the ‘international’ feel that I had in the UAE which is a key point to where I would want to move to.)
