As evidence of Pakistan connection to the Mumbai attacks piles up, India is hardening its stance. The Indian External Affairs Minister Pranab Mukherjee has said that all options are now open, including a military one against Pakistan's terrorist strongholds. Meanwhile, the Pakistan government says it is open to a joint investigation into the attacks.

CNN-IBN debated on Face the Nation if India should target terror camps in Pakistan.

On the panel of experts to try and answer the question were former secretary to the Ministry of External Affairs and former ambassador to UAE and Iran, K C Singh; Senior International Correspondent CNN, Nic Robertson; Pakistani author of A Case of Exploding Mangoes fame, Mohammed Hanif; and Pakistani journalist Naseem Zehra.

At the beginning of the show, 90 per cent of those who voted in said yes, India should target terror camps in Pakistan while a minority 10 per cent disagreed.

K C Singh said that this was not a realistic option for India, but as far as the Government is concerned he said that all options are on the table as of now.

"The time is there for us to exert pressure on other countries, get international public opinion on our side. However, we must remember that Pakistan is a nuclear weapons' state and any attack inside Pakistan is inviting war. The question really is, is that what the Pakistani military wants? Are they trying to disengage from the western side and bring their troops to the eastern side? I think we should put everything in a larger context and not be drawn emotionally into anything the Pakistani army is looking forward to," Singh cautioned.

Mohammed Hanif entered the debate at this point saying that there were parts of Pakistan which were completely lawless and where the writ of the government just did not work but they were not Muzzaffarabad - which was devastated by an earthquake - or Muridke - which is a thickly populated, struggling town in Pakistan's Punjab. 

However, he conceded that there were indeed areas in Pakistan where the government was trying very hard to establish its writ. 

"The Hotel Marriot blasts and the assassination of Benazir Bhutto show that Pakistan was is as much a target of terror as India, but the government of Pakistan is trying very hard. President Asif Ali Zardari has come into power less than a year ago after a very traumatic experience and he is struggling with the same issues that India is including riots, lawlessness and terrorism," said Hanif.
