Simply blaming the pak govt and militants will not end anything. We must see what our govt. was doing in this point of time. For more than a decade this is going on and one very well knows that Delhi and Mumbai are target of such activities. What our RAW, IB were doing? We common man who toll day and night to get a piece of bread and a space to live and no one to back our family if something happens to us should be blamed to live in mega cities ?
