The top-level security meeting held by Indian Prime Minister Manmohan Singh last Saturday was actually a meeting of Nuclear Command Authority (NCA). The meeting, kept under wraps so as not to fuel the current war hysteria between India and Pakistan. Sources, however, denied the NCA meeting on December 20 had anything to do with the current stand-off with Pakistan in wake of the Mumbai terror strikes. They, in fact, stressed the meeting's "only intention'' was "to take decisions on the further consolidation of India's nuclear deterrence''. A meeting of the NCA is held once every three-to-six months to review the further development and management of the country's nuclear arsenal. Under the existing structure, the NCA's political council led by the PM is the "sole body which can authorize the use of nuclear weapons''.
