In a separate intervention, the influential International Institute of Strategic Studies (IISS) said that a vital opportunity was lost when the West failed to carry out adequate reconstruction work after the 2001 war.
Christopher Langton, the head of the IISS defence analysis department, also said that attempts to impose secular laws on a tribal Pashtun society, without the establishment of security, had not worked. At the same time, the war against the Taliban was being hampered because caveats imposed by some Nato countries on the mission have led to a lack of combat flexibility.
Dr John Chipman, chief executive of the IISS, said British tactics of moving into remote areas in Helmand had "acted as a catalyst for intensifying insurgency by drawing the Taliban into open combat. However, it is also true the insurgency has a new energy and the Taliban see ... troops from the European member states - which they regard as militarily weaker than the US - as an opportunity target.
