I think rather than widen the scope of this conflict over cultural, geopolitical and strategic resources we (Obama) could've started to scale down and negotiate from a stance of firm but peaceful resolve. The continuation of drone assassinations involving innocent casualties only deepens the divide and creates more recruits for the fanatical resistance against US interests. We could keep an eye on the more aggressive campaigns and camps without going after every cell loosely affiliated. I think sometimes the more tempered the responses the less interested the adversary is in continuing their long term plans.
Historically many peace accords and conflict resolutions came after intense offensives and there should be a winding down of the tactics we use to strike first.
