My take on this is that UK forces suffer from serious insecurities, in that we are always trying to be clever and complex, when our great strength was being obvious and simple. The IDF is currently making the same serious mistake, by trying to ape the US.

The UK always talks a good game, but real analysis of actual operational achievement never matches the pre-game hype. We are unnecessarily emotional about our armed forces and still have way too many technical and intellectual delusions (FRES being a great example) which let us down badly when we start trying to be too clever.

...and money isn't the problem. The people are the problem. There is enough money in the system. We just have very bad decisions being made by people unwilling to change - but they're all frightfully nice chaps!
