Trouble is, the multinational force in that area, of which the UK is the largest contributer, but also including French, Canadian and Dutch forces, amounts to around 15,000 troops.
But to truly pacify that region, which so far has seen almost non stop fighting, the first combat use of UK and possibly Dutch Apache helicopters, to acheive the reconstruction and other goals, you need around 100,000 troops.
This large resurgence in Taliban strength and influence, is the result of the large scale withdrawl of forces, and attention, from Afghanistan, in 2002, for Iraq.
Not that this particular region was ever an area with significant numbers of US troops.
There is no way the UK can add significant numbers of additional troops, because of in large part, Iraq.
What a mess, promises were made to the Afghan people in 2001, that have not been kept.
