there are some Pakistani trolls online, but i have never met a fellow Pakistani face-to-face that is unhappy with Bangladesh's progress. its not even a topic of conversation on a day to day basis. nobody in Pakistan still talks about 1971 and the crimes that all sides committed. we moved on long ago, but clearly many in Bangladesh havent moved on, and dont want to move on.
I blame Indian influence in Bangladesh not Bangladeshis , just like America has moved away from Pearl Harbor but many still hate the Japanese til this day.
