Kahn lives is the Islamic political world of half-truths, deceptions, and secrets called “taqiyya". In any other religion telling lies and being deceitful is a sin. In Islam, telling lies to protect Allah is a pious duty.  We in the west have no comparable ideology and most western people have a hard time believing such a thing is even possible. That is why so much of what Muslims say compared to what they do confuses us.
