With Pakistan vowing to respond with “full force” to any future aggression in the wake of the deadly NATO strike, the Pentagon has said that Islamabad has the right to self defence and so does the US, Times of India reported. “I’ve seen the comments attributed to General Kayani. I’m certainly not going to speak for him or for the government of Pakistan. “But every sovereign nation has the right of self-defence and the right to order their troops to defend themselves. That’s what my understanding is what he did, He reiterated their right of self defense. We certainly respect that right of his. We have it as well,” Pentagon spokesman John Kirby told reporters. He was responding to questions about army chief Gen Ashfaq Kayani ordering his troops to respond with “full force” to any further “act of aggression” by NATO forces. Kirby also said, “I think it’s safe to say that the incident has had a chilling effect on our relationship with the Pakistani military, no question about that. Both sides deem it to be as serious as it was.”
