N-a-B
Always good to debate. Can I suggest that you have a look at John Ainslie's
meticulous paper on Unacceptable Damage?
What does the UK's conventional force look like when
Successor is consuming such a large proportion of the procurement budget 2018-32? What do we do with an Army of 60,000? RN with <20 FF/DDs?
The point here is choice. And given that no government is going to increase defence spending, then I choose to meet the minimum deterrence criteria (especially within an NATO setting) and spend more on our conventional forces rather than getting stuck with a very capable, but massively expensive, single-role asset to meet a Tier 2 threat.
