Seldom.....
Is that before or after you retire (in the next 18 months?) on a nice big pension....
In the days of the cold war defence spending was about 4.0-4.5% of GDP. Without bothering to research the numbers (google/wiki?) I believe it is now about 2.0-2.5%.
While we are not in the days of the cold war, the world is still a dangerous place, and we are actually in the middle of a shooting war! Defence spending has been run down dramatically over the last 10-15 yeas, while spending on the NHS has gone up by about a factor of 3! However, the NHS is "ring fenced" while Defence has to take its share of pain in terms of saving costs.
I'm not saying Defence should be immune from savings, but it has already been starved of money for some considerable time.
As for the concept that Defence should lose £5-7Bn because you think it has had crap leadership........that logic beggars belief! Especially when you consider that many defence procurement decisions have been politically driven, in terms of "buy British" rather than buy the best, or what the forces actually want!
