"There should be greater amount of intelligence sharing amongst all the countries so that we can prevent a thing like this happening in rest of the world," Singh said. Despite best of the efforts, it is literally impossible to prevent terrorists from carrying out such attacks, he said. "You can work for 365 days a year, terrorists will find one day out of that. That day one does not know whether all your defence would be up or not. Fighting against this kind of a thing is a very difficult business. And that is why, it needs great amount of cooperation amongst all the countries in the world," he said.
Asked about Pakistan's state sponsoring of terrorism, Singh refused to comment. When specifically asked about the US visit of Pakistan army chief Gen Raheel Sharif, Singh said it is up to the US to decide what is in its national interest. "US maintains relationship with all the countries in the world. It deals with the countries as per its own state policy. I am quite sure, US is fully aware how things are in Pakistan. And I am sure they would take action as per their policies to deal Pakistan in a manner they feel fit," Singh said.
