Secessionist movement started as a direct result of settlement and not the otherway where secessionist was subdued by settlers. This kind of wrong policy was tried time and again by a lots of stone headed military type ruler int the world and eventually failed miserably. You can only hold a part of your country only if that part is willing and CHT joined Pakistan and Bangladesh in their own will. But its govt responsibility to protect socio cultural values of its every region. I wont take it lightly if my area Sylhet was overwhelmed by outsiders and our culture, way of life and language are screwed by them. Same goes for every region as long as they are not part of Cosmopoliton city like Dhaka and Chittagong etc.
Either you do not know the history of conflict or you are distorting it for your own convenenience. You may by trying to become forgetful of the past, but, note the following:
1) Paharis sided with the united Pakistan. But, why? Because, the war was to establish only the Bangali supremacy in the then east Pakistan, and Paharis rightfully saw an overwhelming of their position by the Bangalis.
2) So, they sided with Islamabad govt. One Raja Tridib Roy was in Pakistan during the war. Was he a minister in the Pakistan Cabinet, I do not remember. Another Raja Mong Shu Pru also sided with Islamabad. He remained a Minister even during Bhutto.
3) However, the Paharis did not fight like the Razakaars or the Biharis did. They extended basically a political support to Islamabad. It was also a warning to the Bangalis in a separate country.
4) But, after the war, Sk. Mujib visited (probably) Rangamati, and what did he declared like a stupid politician lacking a political science background? He declared in Bengali, 'From today, I PROMOTE you to the status of Bangali.' What a way of talking and woeing an adverse group of people to his formula of Bangalism!
5) Paharis were already against an independent Bangladesh whereby Bangalis would overwhelm them with number. Now, with this declaration by Sk. Mujib another seed of discord was sown and they revolted. Was it a million man revolt immediately? Of course not. This is why, people without information here are claiming that the revolt was caused by the settlement later on. It was just the opposite.
6) Now, let us see how the settlement of Bangalis occurred. BD military mobilized troops in the CHT and took stern actions against the rebels and naturally it sprerad to the entire population. So, BD govt led by President Zia was forced to settle people who are racially Bangali, so that the tide of battle could be turned in favour of the govt.
These unwanted events have occurred only because of AL's racist policy. AL believes this country belongs only to Bangali, and whoever is not already Bangali must come forward and accept their kind of ignorant Bangali nationalism. The point to be noted here, this ill-conceived Bangali nationalism insists that the country is to be inhabited by no nationalities other than Bangalis.
About land distribution, I do not like to elaborate here further. But, I must say Paharis are free to buy land and build their houses in any part of the country. There is no restriction to these. Similarly, the CHT should also not be kept off limit to the Bangalis. Bangalis have equal right to that part of the country. Mroe to the above, the GoB retains the right to distribute lands to any one who is serving the interest or the unity of the country.
