Re-imagine the "War on Terror"

I just saw this article on the BBC website: US war costs 'could hit $811bn'. I'm pretty sure that those terrorists and other insurgents aren't using so much money to create panic. Perhaps the "powers that be" in Iraq and Afghanistan should ask the Indian government on how they tackle terrorism. After all there have been insurgents and terrorists in India since independence. There could be learning opportunities here! In one good example, the state of Punjab in India had a major insurgency in the 80s. Terrorism was rampant. Now however, there is no terrorism in Punjab. On the contrary, Punjab as a state today is peaceful and has some of India's biggest export industries, enriching the local populace considerably.
