War is not nice, at least according to Barbara Bush. Anyways, if there was another war, I'd really hope that Argentina won (I can't really say otherwise, I feel closer to argentinian people in all ways). Some countries also need a "Being humble: How to". If the UK dropped all the colonies it still posseses (or rather say, that the Crown posseses), it would lose a lot of problems. They could start by letting go of colonies within friend's (or so told) territories, like Gibraltar.
Cheers
