So this just your own personal rant without any material evidence this is an issue in Pakistan. I certainly have never heard of GOB refusing to accept its citizen. You are free to have whatever views you have and I suspect you are angry with Bengalis who settled in Pakistan prior to 1971.
Rohingya are not bangladeshies , they do not speak Bangla, however we are cousins.
The Burmese have been tormenting these poor people for many a decades. We house millions of them in Bangladesh.
Hasina position was the only logical course of action. It prevented the Burmese from ethnic cleansing the Rohingya in their entirety. Did you ever hear of them before Bangladesh closed boarder? You have not because Bangladesh has to its ability housed them.
BD action directly bought the focus on the Rohingya and its in the international eye. Burma is slowly moving to grant them citizenship. You should read up on the background and the issues at stake.
I am sure you would agree protecting your boarders are the responsibility of Pakistan from illegal intrusion, similar to what we did in the Rohingya situation .
If illegal immigration is a systemic issue than there are systemic instruments to tackle it. If you are merely trolling for the heck of it it's also cool but you would do not cover yourself with glory and much less when you align yourself with hindutva turds.
