I m not sure that removing the western military presence from say Iraq and Afghanistan, or even persuading the Israelis to top the killing in Gaza would result in the evential somnolescence of the Taliban and Al-Quaeda: surely they object not only to the western military invasions but also to the western cultural and economic invasions (Coca-cola and MacDonalds and rock music, dancing and bikinis - oh, and internet porn) that they see as immoral and tending to undermine their religion(s). Are they not similar to the Western crusaders in the period say 1,000 AD to 1,300 AD, running a military invasion for religious reasons?
