Umm,have you ever heard of the (proposed) policies of the Maoists in Nepal??First it's the usual stuff of finishing off the Monarchy etc & then to distance Nepal from India.The Indian military has opened several lines of credit enabling the RNA to buy Advanced light helicopters,'Lancer' CAS choppers,artillery & other weapons.I find your logic of India abetting the Maoists in Nepal in order to protect itself bizarre to say the least.The Maoists in Nepal are ideologically affiliated to their buddies in Bihar-what makes you think they will stop with Nepal??The US,UK & India have all increased help to Nepal with the express purpose of weakening Chinese expansion to the region,with the UK having given money for 2 MI-17 choppers.
I once met an Indian evangelist working in Nepal who said that it is common knowledge there that the current king & his offspring,Paras engineered the assasinations of King Mahendra & his family in 2001 in order to assume power.Gyanendra was supposedly not in favour of greater democracy,which would dilute the monarchy's power.It was Mahendra,who under Indian pressure,established a democratic government in Nepal.Hence Gyanendra was seen by many intell agencies in India as being against New Delhi & therefore pro-Beijing.
This is one of the few examples in history where the transition to a constitutional monarchy was probably an unwise decision.
