First of all, I have said numerous times that Bangladesh economically & HDI should have been doing a lot better than Pakistan & India because from three sides you are surrounded by India, Bangladesh's creator, ally, protector and big market, no other country is waged overt/covert war on Bangladesh. So, you don't have to worry and spend on your defense which provided you huge saving and almost 5 decades to focus on your economic and human development, considering the time and opportunity you got the performance isn't that much that you start claiming to be economic super power like your compatriots try to portray. Over that figures given by your government aren't trustworthy for us to begin with.
On other hand in our east, we have dispute over J&K with India since partition (Although hypocrite Bongs now side with India over it but dispute was there between 1947-71 as well when your forefathers were east Pakistanis). On our western front, Afghanistan didn't recognize Pakistan and tried to invade Pakistan to annex KP and Tribal areas, We had troubled relations with delusional Afghans who still think territory till Indus is there and have to deal with proxies, later on soviet invasion, civil war, US invasion in Afghanistan. Iran since revolution have it's own agenda of expanding it's influence which we have to deal with. So, geographic and geopolitical factors for Pakistan have been tough but still till "War on Terror" Pakistan's GDP per captia was higher than India, We are at war for about two decades which have taken toll on our economy, so any comparison under this circumstances is comparing orange with banana. As we have improved our security situation, give us few years to recover than we will see where we stand.
Finally, the poster talk about Islamisation. Well, factually it was Bongs who introduced religious political card in subcontinent. As far as Pakistan is concerned, we have realized the mess it create although had to pay hefty price but we are on track to root it out. However opportunists bongs in general were using religion just as tactic for their interests so it was easy for them to ditch it as per will, but that's not the case in Pakistan. So, it will take little longer.
