This was to happen, sad very sad that so many kids lost their life.
Now why I said this was to happen because its is making of their own, what you expect when you breed fundamentalists, madarsa educated scum bags to gain strategic depth to defeat a nation who is larger by more than 7 times in every respect. Such incidents will happen on regular basis until and unless Pakistan as a nation stop its medieval mentality. Targeted killing against any one solves nothing be it against al-Qaeda, TTP, Taliban or any other enemy force, USA did it against Iraq and Afghanistan and what they got? Is Iraq and Afghanistan more stable now?.
Pakistan repeated the same mistake, they not only killed Bad Taliban (that is what they call them, since Good Taliban is their asset) randomly but also targeted their family members too without going through proper channel of justice, I can understand such tactics against suicide bombers or terrorists who are willing to kill or get killed. No doubt their are certain situation when their is no other way other than killing but that is only temporary solution. If you want to solve a problem then first you need to understand the root cause and then plan strategy to counter it, taking into account every possible repercussion and long term effect, but sadly I don't expect this type of logical reasoning from Pakistanis(by Pakistanis I mean the people who are running the country, esp. Army ISI etc. and not the general public).
Instead of retrospecting and understanding the real cause they will now start cooking conspiracy theories that how India and other western nation is responsible for this, its not their fault. Soon you will hear story about involvement of CIA, RAW, MOSSAD............Pathetic. Nation build on fake ideologies and promises.
