This offer was accompanied by yet another recounting of Pakistan's role in fighting terrorism over the years, and the casualties and economic losses it has sustained. It has little credibility because of Pakistan's past record in cooperating with India in investigating terrorist attacks. Pakistan never acted on several dossiers on the 2008 Mumbai attacks.
