It's double standard at their best. They always mention killing of Benazir as something that has never ever happened in another country! Benazir was an opposition leader, not a sitting Prime Minister. No head of state has ever been killed in a terror attack in Pakistan.
Our neighbors to the south have failed to protect not one but three prime ministers (heads of state) - Rajeev, Indira and Mohandaas Gandhi - all murdered in public.
I rest my case.
