It is not only the PM's integrity is at stake, but it is the nation's. Both China and Pakistan must feel happy to note the happenings in Indian on the nuclear deal. While Chinese interests are protected by Karat and Co. we do not know who protects those of Pakistan. May be the Congress and SP represent Pakistan.Look at the stand of UPA allies. They including Congress are interested only in their power and position and are not hesitant to sacrifice the national interests. Nuclear energy is must for India which is facing energy crisis with the increased oil prices and stagnanat production of oil in India.
