I think striking in SW will only take care of the problem in SW not anywhere else in Pakistan.

SW is no foreign country whose borders are drawn and protected formally by our forces. It is not even densely populated..

Right now its like a safe haven for any criminal who is involved in kidnappings, murder, robbery and what not.
This is the mother of all diseases. Once handled, others will become easier.
