Politicians are root cause for such kind of violence... there are the people who provide money to use these naxalite during elections to capture booth or to kill other contenders... all the money alloted for upliftment of tribals goes into the pockets of politicians..... unless we change our political system.. nothing is going to be right.... we cleared punjab.. now its andra, bihar, chattisgarh.... if we clear this there will be some other state.... if you look a t the data 90% of our MPs has some charges of murder, kidnapping or extortion... they can make laws like reservation in higher intitution just for shake of 3 years of power... how can you expect good things from such people..... these states will continue to suffer along with all common people of india unless we change our political system... they will never take any steps to tackle this problems... if all the people of india will get educated and start knowing about world... non of these politicians will get a single vote... they want the poors and uneducated of INDIA to remain in same way to retain thier posts.....
