There certainly is some merit to your point, but as you have agreed - there were many other things. In my opinion, Prachanda was more instrumental on this than Bam Dev. Call them corrupt, bad..whatever..the process wouldn't have gone through if Maoists were against it. It could be true that Sushil's appointment of Bad Dev softened Prachanda's stance, but Bad Dev's mere appointment didn't get it done.
