Bhai, please try to understand that we are neither US nor UK. You are talking about the model adopted for legal/illegal immigrants by the US/UK. It worked for them, albeit partially, for their economy could absorb the insult but this is not the case with Pakistan. Our resources and means are limited, actually very limited. We have over 70% Pakistanis living under the line of poverty, we are dumping great deal of resources in war on terror, we are simply no longer capable of supporting the Afghan refugees. We have hosted them for 35+ years, it is time for them to go back and build their own country. So long they remain in Pakistan, their government will remain relaxed and would do nothing to mend their difference and work for the development of their country. Assimilating Afghans in our society is a non no, for they have their own country which needs them and they must go back. Because we made a mistake by allowing them into Pakistan and roam freely does not mean we continue with our mistake. Mistakes are always fixed, not repeated or continued.
