PN, It was your point of "we don't have any other world interests other than the oil coming out of the ground in Libya and Nigeria" that I take issue with.
And UK MPA has done what to support this?
"generals always fight the last war" is what springs to mind when people say things like this, you have absolutely no evidence to substantiate your claim that a nation that has an extremely heavy reliance on shipping across the globe isn't going to need a MPA capability in the future. Just because it isn't immediately obvious now in some hypothetical African scenario doesn't mean the capability isn't going to be seen as in indispensable asset in many, many other future scenarios.
