Not even US (the mighty super power) is save from terrorism but the truth is that their organizations want to save their country from core of their heart. It is not the case here. If you don't take output from you people, then nothing will change.
You cannot kill the thoughts of every terrorism. You can start it but it will not end terrorism.
After all these years. we never did anything to wipe out these scumbags and when someone tried to do it, he is stopped by some other organization, government, judiciary or political figure & party.
If we kill them time to time, it will not give them time to regroup and grow bigger. That's the only way..
