Closing your eyes doesn't change reality. No one is denying that terrorism is a national (rather international) issue but there is a clear sectarian angle to the ongoing terrorism in Pakistan. International organizations like UN, Amnesty Int, Human Rights Watch etc. have all condemned and expressed concern over the ongoing Shia targeted killings and Shia Genocide in Pakistan. Now don't tell us that these organizations are pro-Iran/pro-Shia too ..... Also, our case on Kashmir is built entirely on Resolutions/reports by theses international organizations, why double standards ??
It didn't start with the Syrian Civil War. Shia targeted killings have been going on in Pakistan since 1960s, at that time Iran was ruled by the Shah and Arab secular Nationalism (not Political Islam) was the dominant ideology. Situation became worse after the Zia regime created and patronized anti-Shia sectarian outfits in 1980s.
