I agree that there were so many other things that came together at the time. I think that Sushil Koirala won the psychological battle when he waited three months to appoint his cabinet members. After that he had already won over the opposition through his selflessness. And Bam Dev Gautam, a politician known for getting things done, on his side made it easier for his government to get the majority of votes. I am giving credit to Koirala's character, leadership and patience, and understanding of urgency of situation when the time was right.
