Just a personal view but I think a few of you are missing the point. Looking at the present governments past performance and the performance of post WW2 Labour governments I think they will be very happy to see the armed forces continually reduce until they are about the size of the Home Guard as this would leave them with a lot more money to squander on any useless project they can think of.
Labour politicians are not Service minded in any way at all, they can only think of themselves so the idea that, "When things get bad enough they will have to do something" is a pipe dream, things are going exactly as they want them to.
