Take the Falklands for example, without being an overseas British territory they'd have been snuffled up by Argentina. I dare say it cost more than it was financially worth to save them but it sent a message not to **** with us or our territories. Interestingly the other day I saw on my Youtube feed that we had successfully managed to nuke the US twice during research training drills. The fact we were asked at the time to take part and the outcome we achieved means we get a certain amount of clout and regard / taken seriously.
