@TK, thats really an excuse. Even if there were people in India who helped the terrorists, it does not absolve the actual terrorists who did the deed. Just because possibly the accessories to the deed were Indians, it does not diminish the fact that the perpeterators were Pakistanis.
On travelling across the country, Indian security's inefficiency does not provide a justification for such tasks. Other wise your logic can be applied to Pakistan's situation as well where despite over a 1.5 lakh military presence in the NWFP region, the Pakistani terrorists are able to attack and kill civilians in Pakistan all the way down in Lahore...
Its not an excuse, rather it is the truth.
And how many times Pakistan based terrorists have been doing such actions in India, except for 26/11, where also ID of one of the guys has been established and that incident also has lot of unanswered questions and many ambiguities to raise many doubts.
Except for Kasab, how many Pakistanis have you caught in the act of doing terrorist things ?? None i believe, and those who were intercepted, got killed and nationality or origin unanswered.
Don't compare the situation with Pakistan, as the story is different. In your country, your own Indian countrymen are involved in inviting and facilitating the ones from this side of the border, while the ones in Pakistan are doing it themselves with financial support coming from across the border.
Plus, as said tell me the number of times Pakistani's have been involved in attacking Indian cities except for 26/11, 26/11 which itself is very controversial.
So in saying that get the things in order on that side of the border is right, as if things get OK there, no one will be coming from this side of the border. With 150,000+ troops and relentless operations, the taliban still lurk in those areas, thus even whatever we do against LeT or others, they still would be there and will do whatever they want to make things go worse between Pakistan & India, as that is the easiest thing which they can do to take off pressure from themselves and make the two go to a war.
Pakistan has no benefit whatsoever in making such kind of attacks, rather it is the only party which has everything to lose from such actions, which is precisely what these ones want, the ones sitting in your country and the ones sitting in our country.
And except for 26/11 (which is also doubtful), all the rest has been Indians themselves, not Pakistan or Pakistanis.
