India and the United States have asked Pakistan to move expeditiously in prosecuting those involved in the Mumbai terror attack. They also reiterated their commitment to bring the perpetrators and supporters of the Mumbai terror attack to justice. Addressing a joint press conference after the first Homeland Security Dialogue in New Delhi, the Home Minister Mr. P. Chidambaram and his American counterpart Janet Napolitano called for effective steps by all countries to eliminate safe havens and infrastructure for terrorism. Both the leaders discussed their cooperation in the investigations into 2008 Mumbai attack and committed to expand bilateral cooperation to further strenghthen their capacity to secure their countries and protect their people. Ms. Napolitano said that US and India face common threats and they must develop common approaches to protect shared critical infrastructure. In reply to a question, she said that Lashkar-e-Taiba is an organisation that is of the same ranking as Al Qaeda related groups that seeks to harm the people and take innocent lives. On the issues of revelations made by terror mastermind David Coleman Headley, she said after the trial is over in the Chicago court, India will be given more access to question the accused.Earlier, Mr. Chidambaram in his opening remarks said that both the sides discussed issues like port, border and coastal security, mega city policing, illicit finance and counterfeiting, cyber security, capacity building and technology upgradation. He said the next round of dialogue will be held in Washington in 2012.A joint statement issued after the dialogue said that both the leaders decided to strengthen agency-to-agency engagement including in the areas of intelligence exchange, information sharing, forensics and investigation, access and sharing of data relating to terrorism, security of infrastructure, transportation and trade.Earlier in his opening remarks, Mr. Chidambaram has accused Pakistan of using terror as an instrument of state policy. He said, different terror groups operating from safe havens of Pakistan are working in coordination and the society is also getting radicalised there. He added that Pakistani economy has weakened, the state structure in Pakistan has become fragile and that is why India perhaps is living in the most difficult neighbourhood in the world. Mr Chidambaram said, the global epicenter of terrorism is in our immediate western neighbourhood and the vast infrastructure of terrorism in Pakistan has for long flourished as an instrument of state policy. He said, terrorist infiltration or fake currency inflow does not only take place through our western border, but is often routed through countries that we share open borders with. The Home Minister said, in a world of complex challenges, including new and emerging forms of threats, terrorism remains a principal challenge for India and the United States. He said, the events of the past few days, especially inside Pakistan, speak to the successes and to the enduring risks and challenges. He said, despite extraordinary efforts and significant successes against the forces of terrorism, its threat remains strong.The Home Minister said, this is an important milestone in India-US relations and adds a very important dimension to the growing strategic partnership between the two countries. He said, it also implements one of the key strategic outcomes of the visit of President Barack Obama to India in November 2010, during which Prime Minister Dr. Manmohan Singh and President Obama announced the Homeland Security Dialogue.
