THAT the five nuclear tests at Pokhran have temporarily silenced the Opposition needs no elaboration. In one voice, parties across the board have said they "hail the efforts of our scientists". No party or Opposition grouping has dared to go against the tide of national fervour and question the nature of the security threat that led the BJP government to exercise the nuclear option, kept so long in abeyance. Though in private Opposition leaders point out that the tests may have been hurriedly conducted to give a shot of adrenalin to the BJP, they admit that it is too early to raise questions and run the risk of being dubbed anti-national.
