Article 1 of the UN charter states that the UN shall maintain international peace and security, and to that end, take effective collective measures for the prevention and removal of threats to peace, and act for suppression of aggression or other breaches of peace. In the past many months, Pakistan has been repeatedly attacked by the USA. Pakistan government is in great hurry to approach UN for investigating the murder of Benazir Bhutto-something that it ought to have done on its own. But it has shown no inclination, or urgency, to lodge a complaint to the international body for being under repeated attacks by a delinquent superpower.
