Nobody is blaming Pakistan for the assassinations you mentioned, nor for Maoists or Khalistan movement.
But we blame you for harboring Hafeez saeed likes. Why Pakistan proudly harbors terrorist organisation like Jamad ud dawa, Lashkar e taiba, jaish e mohammad and Dawood Ibrahim who have killed thousands of innocents through bomb blasts in Indian cities? India has not forgotten those and never will. India was earliest victims of Islamic terrorism emanating from Pakistan, till rest of the the world faced Islamic terror. More than 80,000 AK-47s, 3000 machine guns, 1500 rocket launchers have been recovered from Kashmir. They were products of your open gun market like dara adam khel in Khyber agency. It shows the nature of a country which allow a market like that to thrive.
Pakistan was safe till 9/11 and till US forced you into war on terror which turned your strategic assets and mullahs against Pakistan. The glory days when army, mullah and especially super power US all were happy are over. Till today Pakistan openly supports taliban. See Bangladesh, inspite of being a muslim dominated country facing radical islam threat, is doing its best to counter it. Pakistan is still confused with good terrorist, bad terrorist bifurcation. It still has support for talibans, sharia law, blasphemy law and strategic terror assets. Till Pakistan takes care of these no CPEC or any EC is capable of bringing investments in Pakistan. Even your iron friends have invested in mobile manufacturing and even RnD in India.
