India News: The Janata Dal-United (JD-U) Tuesday ruled out a threat to the Nitish Kumar-led coalition government in Bihar even if the BJP walked out, while the latter termed the attack on its leader Narendra Modi as "unfortunate and objectionable".<br /><br />"If BJP withdraws its support and ends the 17-year alliance with the JD-U over Modi, the Nitish Kumar government will not fall. The JD-U has adequate numbers to run the government alone," a senior JD-U leader considered close to Nitish Kumar said in Patna.
