9/11 was not done by Pakistan it was an 'inside-job' by the US. Please check out the research done by US Nuclear Physics professor, Steven E Jones. Also read the books by famous American theologian, David Ray Griffin, titled The New Pearl Harbor: Disturbing Questions About the Bush Administration and 9/11; he 9/11 Commission Report: Omissions And Distortions (2005); Christian Faith and the Truth Behind 9/11: A Call to Reflection and Action (2006). I request you to search for truth and not propagate falsehood, even tough the truth is too bitter to swallow
