When the Quran says killing one life unlawfully is like killing the whole of humanity...what does it mean? Islam does not teach collective punishments...you hurt A...so A punish your whole family tribe or nation...even those people close to you who have not caused A any harm. A will be held responsible for murder in the akhira. If A claims that the others were just in the way 'collateral damage' they will be asked if they took all precautions to prevent harm to others.
Well when America was attacked 9/11 it did nothing to weaken them. In fact it gave them the excuse to attack Afghanistan, Iraq, and many many Muslims around the world. I would argue the American Industrial Complex has become better empowered after the war on terror was started...they have all profited greatly both in terms of money and strategic gains. Patience or sabr is a virtue, sometimes being patient and biding ones time is better.
The Pakistani military also gains, the military is owned by a few wealthy families...they control the wealth of the whole of pakistan, attacking them only pushes them into the hands of the Americans and their money lenders who further gain control of Pakistan. Better in my oipion to be patient, to build up your own power and to work at grassroots...
Mujadid Alfi Thani the Islamic renovator of the deen was sent to prison by Al Akbar, from there he started working to implement the deen, and he wrote letters to people close to the ruler trying to win them over. He did not start civil unrest. The Jihad you are speaking about does not help Muslims or Islam....it is valid when Muslims have created a government then from there they declare jihad against other nations....this is the true jihad it is calling others to the deen nothing more...no defending the land, or the lives of other Muslims...simply to call others to the deen...this is fee-sabililah. The siratul mustaqim is a path of moderation.
