The BJP was a political pariah till it got a shot at Government through the trojan horse of the NDA and its merry band of freebooters.
Vajpayee had (before then)to face the ignominy of a 13 day government as no political party with any sense of decency was willing to associate with the BJP!
The BJP had to lump its hubris driven 'ideology' to get a shot at governance with strange bedfellows like George Fernandes who earlier wrecked the Janata Party over the dual membership issue (RSS links).The sordid sight of the PM and DPM (and recently chief ministers) grovelling at Nagpur did not bother the super patriots who had deep concern over 'dual membership'.
The Gujarat episode was the icing where the BJP called the bluff of the TDP and told them that they had no choice but to accept the governments unwillingness to follow Raj dharma (and to show Modi the door).
It is a sad joke to now suggest that the BJP was at the whims of its coalition partners.
It used the coalition partners to get into government and remain entrenched without a mandate!
The BJP had no role to play in the nuclearisation of India.Thier achievement is the overt nuclearisation of Pakistan.
