For you may be half century of sponsoring terrorism in the neighborhood has no meaning, but for us the victims of Indian terrorism, who have lost hundreds of thousands of children, nuns, nurses, doctors, professors, it has a very strong meaning.
It is as if telling you that "so what if Mumbai happened, these kind of small things happen". What would be your reaction to that?
So stop playing this victim card. And finally take some concrete action to tell the neighboring countries that you mean business and will no longer train/arm/finance terrorists to carry cross-border attacks.
That will go a long way for peace in the neighborhood.
