You forgot to add that a major reason for the lack of investment in the sort of warfare that UK AF have been involved in in recent years is the insistence by the Top Brass to procure equipment fit for the Cold War, but not the kind of asymmetric warfare fought in Iraq and Afghanistan.
The Cold War equipment being delivered today was ordered and committed to in the Cold War. Equipment is procured to serve a long time and has to be flexible and capable of responding to a range of different contingencies. If you procure Russian helos today only to find that tomorrow you're confronting the Russians how valuable would your investment have been? The way forward is to have a range equipment in Service which is flexible enough to be used for lots of different things and designed to be reconfigured and upgraded.
