Well, it says there's nowhere near enough troops, planes and money, and that the current government is useless. (That's him talking about Afghanistan, not the UK). Also says that some NATO members like France, Germany, Turkey, Spain and Italy are not providing fighting forces and that the Poles coming next year will be poorly equipped.
Well, it also says how to improve the situation, and what all the various hostile groups are about (in fact that is the majority of the report), but it all has to start with more troops on the ground.
What I liked was his comparison with Iraq:
Land Area: 432,162 sq km
Population: 26,783,383 people
Coalition Forces: ~162,000 people
Land Area: 647,500 sq km
Population: 31,056,947 people
Coalition Forces: ~32,000 people
That's five times less forces to control a country that is about a third bigger.
