Militancy in the north east is too complicated a matter for even the best brains to understand, hence such goof ups like mistaking the origin of a militant group can be understood.
What is more surprising is that even the educated elite of our country is absolutely clueless as to where is the Northeast region, how many states & capitals. For many, nothing exist beyond Kolkata!!!!
The level of Ignorance about the North east states is stupendous, probably one of the reasons why people of this region feel alieniated & provides the chance for these militant groups to flourish.
