So when he says that he will deport Bangladeshis, how do people infer that he is talking about all those who have migrated to India since 1947? That is not legally possible and no one can attempt to do that. Even those who migrated after the
‘Nehru-Liaquat Agreement’ of 1950 have legal sanction and cannot be deported. Those who migrated as a result of the Bangladeshi liberation war are covered under international agreements on displaced persons and refugees. India had allowed them to settle and earn their living in the country, even giving them concessions like non-transferable housing land at low cost (as in refugee colonies in Kolkata and other places of West Bengal). Most of them have become Indian citizens through naturalization with their children having acquired Indian citizenship by birth and that fact is indisputable.
But if someone makes out a case for retaining those who are entering India illegally since then, no right thinking Indian will tolerate it. Taking advantage of a porous border and corrupt security forces, illegal Bangladeshi immigrants have been entering India in West Bengal, Assam and Tripura.
