Re: Maoist Attack on Indian Troop!
Indian, Nepalese, Peruvian and some other Maoists see themselves as fighters against 'revisionism'. They are more or less supporters of the 'gang of four', and would have preferred the cultural revolution to end in a different way. In other words, they are opposed to the China's reforms in the late 70's, saying this amounts to capitalism.
There is a second matter, which is that also in the late 70's (but earlier than the economic reforms), China cut off all ties and aid to revolutionaries around the world. For some of the people that supported China this was a factor.
However, when he was prime minister, Prachanda of Nepal visited Mao's home town, and though he has never taken any words back, all indications are that he gets along well with the Chinese leadership. It was India that maneuvered to stop him from taking the post of president after he won the elections, and has been working to marginalize the maoists since.
In my own opinion, It is possible that China would have continued making progress without the reforms of the late 70's, but it would have been much slower, as it would not have been able to utilize foreign capital, and technological absorption would have been much slower. As well, it would not have benefited from world trade as much as it has. Moreover, if it had continued supporting revolutionaries in Nepal, India, Burma, Malaysia, Thailand, Bangladesh, etc., it would be impossible to have a friendly relationship with the governments in these countries, and countries wishing to encircle China would have used the resulting antipathy to encircle it. This would have forced China into a situation of having to spend the capital available for investment and growth on military development instead, much like the Soviet Union or North Korea today.
