Bombing a country or killing people isn't the answer to every problem. Especially the problem of hatred. Terrorism is a mere fraction of the problem of hatred. Bombing and revenge killing infact adds fuel to his hatred. Then why don't we go ahead and bomb AP for naxalites or Assam for ULFA.
What is needed is to accept that there is a problem in the first place, and to be open to ALL possible solutions.
The first step is to hear the other side out. What makes them bomb themselves along with hundreds of innocent others who are in no way related. And then work to change their thought process rather than brand them into a category and shun them away.
Granted not even a single soul lost in the blasts is worth it. Not even one. So don't worsen it by killing even more, even terrorists. Go to a room, talk things out, put pressure, financial or otherwise. Instead issue is kept alive, on both sides of the border, for political reasons.
And please stop this US crap. This terrorism, Al Qaida, LeT, JeM, all these are US created Frankensteins during the cold war. And now the US is creating even more due to Iraq.
Solution in one sentence - Change the mentality, not the people.
