British involvement abroad has painted a target on their backs at home, I don't think it's a far-fetched conclusion to make. If there's evidence on the contrary, provide a link instead of saying 'It's not so just because I read an article somewhere'.
My point (though based off a couple of articles that make a slightly different point) is that even the best foreign policy isn't going to work 100% of the time without making enemies. That doesn't necessarily mean our foreign policy doesn't need some adjustment but a lot of people seem to want to jump fully to an almost isolationist soft alternative in response to the times when it has resulted in an impact felt at home.
