Signalling that the UPA government is still hopeful of taking the Indo-US civil nuclear deal forward, External Affairs Minister Pranab Mukherjee today said the Government would take a "sense of the House' on the deal before it is taken up for ratification by the US Congress. "Even if you have the right to sign the treaty, for implementation of the international treaty, you require legislations and these have to be done by Parliament. If at that point of time, Parliament refuses to move the legislation, the international agreement will be of no use,' Mukherjee told reporters. His remarks come ahead of the May 6 meeting of the UPA-Left mechanism on the nuclear deal in which the Government will address the Left's reservations, given in the form of a questionnaire, on the draft safeguards agreement with the International Atomic Energy Agency (IAEA). The timing of the meeting holds significance as IAEA directors will also be meeting during that time to discuss their budget and in case of any breakthrough at the May 6 meeting, there could always be a possibility of the directors holding a special session of the IAEA Board to discuss the India-specific safeguards agreement. Meanwhile, CPM leader Sitaram Yechury has said "we will consider what the Government will report to us on its talks with the IAEA. On that basis, we will take the issue forward.' Asserting that the Left opposition to the Indo-US nuclear deal continued, he said the Government was committed to consider the findings of this committee while taking the next step on the nuclear deal. On the Left charge that the nuclear deal would impact India's foreign policy, Mukherjee said: "All these points have been examined, X-rayed from different angles. But on certain issues, perceptions differ. But perceptions change with the passage of time.' "I do not say that the majority of Members of Parliament are supporting it. To some extent, the judgment is premature in the sense that the process is not yet complete,' he said. On Left apprehensions on the Hyde Act, he said, "They are trying to juxtapose it (apprehensions) on the Hyde Act. It is the problem of the US to implement it. I have no obligations. If the US President finds it difficult to implement the Hyde Act, I can't take responsibility of solving his problems.' Mukherjee said India's nuclear policy has also changed with time, noting that at one point of time the country had decided not to go for civil nuclear agreement. India, he said, decided to go for the deal after finding that it was universally viable, non-discriminatory and that certain countries would not have the monopolistic right to acquire technology. On political parties seeking ratification of bilateral agreements in Parliament, he said there are both plus and minus points.
