You can not change the perception of people who are paid to make lists and write articles or Govt who are driven by their own national interests or lobbying, you focus on the good with the people, So far Americans I've met and work with, many know very little about Pakistan and those who do have positive views on it, many even show interests in visiting it when i showed them the Pictures of Pakistan, and told them how hospitable Pakistan is and how cheap it is to travel there, but as I said these lists are nothing but tactics to discourage the people of Pakistan and you can see it in this thread there will be people who will curse Pakistan and its people for being worse than Firons, but In reality everything they blame Pakistani's for has been and are been done by many other countries and yet their Passports are still better, just take South America as example, many illegal border crossing, gang related violence, money laundering , drugs, sex trafficking they do everything what ISIS or AQ has dream of doing in American x100 times and yet they get away with all of it, you don't see many S.American countries or its people being sidelined that much, why? If anyone posts videos of cartels killing and torturing's victims that will make ISIS look like pacifists.
bhai many of such people are Overseas, we go to America and get American Passport and suddenly we pretend to be more American then the founding fathers of America, we forget where we come from and what our roots are, this kind of People are as they say " Bin painde ke Lotte ", and that include one of my uncle who is currently living in Canada, talk to him and he will make Pakistan worse than living under ISIS, and yet he lived 24 of his years in Pakistan, got his engineering degree from NED, get job on that behalf and whatever, and told same douche ( yes my uncle is douche ) curse Pakistan and ashamed to be called one.
