Operation Nemesis was a plan concocted by Armenian Nationalists to kill the main people responsible for the Armenian Genocide in the 1920s. People like Djemal Pasha and Talaat Pasha, two out of three of the "Three Pashas" were killed, for example, along with one of the presidents of Azerbaijan.
When Bangladesh gained their independence the main people responsible for the Bengali genocide such as Tikka Khan, Yahya Khan, A. A. K. Niazi, A. Q. Molla and Ghulam Azam were not tried for the crimes immediately following independence if at all.
Could a Bangladeshi version of "Operation Nemeisis", where Bangladeshi Nationalists try to kill people like Yahya Khan, Ghulam Azam etc. be carried out? And if so, what would be the reaction in Pakistan to seeing people like Yahya Khan be killed? Sure, Yahya Khan was universally despised by Pakistanis and was stripped of his honors following 1971 but they would be shock at one of their former presidents being killed. I've seen a lot of Bangladeshis online hate Zulfiqar Ali Bhutto for refusing to let Sheikh Mujib become Prime Minister of Pakistan, so could he had been a target for assassination, and if Bhutto is killed what would be the reaction then?
