In my thinking, India can choose NO CA over incredibly adamant (anty Indian force-Jhala Mao collision) both in government and CA.  Given the fact that there is 1) no leftist influence in Indian government, 2) leftist party lost election in India, 3) increasing Maoists insurgency in India, 4) increasing pressure of west/Europe over indian failed policy after 12 pt agreement, 5) increasing Chinese influence in Nepal,  India definitely would have revised its strategy. Indian conventional thinking of destabilizing Nepal has made more people anti Indian than it has been able to made vigilante supporter. It appears that Indian establishment now wants stable Nepal and stable ruler with whom they can negotiate and gain out of it.  I think if this government (anit India collision) continues till next three months, I see the end of CA right there. If not, then SR Deuba or Dr. Bhattarai will be the next PM.
