WASHINGTON - Sovereign nations have the right to protect themselves, US President-elect Barack Obama said Monday, when specifically asked if India could follow the same policy he advocated during his election campaign - of bombing terrorist camps in Pakistan if there was actionable evidence and Islamabad refused to act on it. "I think that sovereign nations, obviously, have a right to protect themselves. Beyond that, I don't want to comment on the specific situation that's taking place in South Asia right now," Obama told a news conference after unveiling his top national security team in Chicago where he said he has been closely following the situation on the sub-continent in the aftermath of the attacks. "I think it is important for us to let the investigators do their jobs and make a determination in terms of who was responsible for carrying out these heinous acts, he said. "My administration will remain steadfast in support of India's effort to catch perpetrators and bring them to justice. I expect the world community will feel the same way," Obama said, in one of several references to the events in Mumbai. Obama said the United States will be engaged in "very delicate diplomacy" with regard to situation in South Asia, and he was confident that the Pakistani government would follow through on its commitment to cooperate with the investigation. "We are going to be engaged in some very delicate diplomacy in the next several days and weeks," said Obama, who takes office on January 20, 2009. At the same time, he reiterated that the US has one president at a time. "I would be monitoring the situation closely, thus far I think the (George Bush) administration has done what is needed and try to get details of the situation and my expectation is that President (Asif Ali) Zardari of Pakistan, who has already said he will fully cooperate with the investigation, will follow through that commitment." He reiterated his incoming administration's resolve to curb extremism with a comprehensive approach, combining security, political, diplomatic and economic elements. "What I can say unequivocally is that both myself and my team that stands beside me are absolutely committed to eliminating the threat of terrorism and that is true wherever it is found. We cannot tolerate a world in which innocents are being killed by extremists based on twisted ideologies. And we are going to bring the full force of our power not only military but also diplomatic, political and economic to deal with those threats not only to keep Americans safe but also to ensure that peace and prosperity can exist around the world." Obama said he has spoken to the Indian Prime Minister and Secretary of State Condoleezza Rice has briefed him about the situation.
