Malala Yousafzai didn't need to win Nobel Peace Prize
And this video shows why (though she would undoubtedly have been a more worthy Nobel laureate than some recent recipients - like Al Gore, Barack Obama and the European Union).
In the West, Malala's words about hitting a Taliban assassin with her shoe would be interpreted as a (rather hysterical) act of self defence, hence the laughter of the audience. In Islam, however, showing the sole of your shoe or throwing a shoe at someone is a sign of great disrespect, as President George W Bush once discovered. In that religio-cultural context, Malala is declaring that she would let the Taliban know that she did not disrespect them before they proceeded to kill her.
There is, in that remarkable gesture, more than a hint of "forgive them, for they know not what they do".
"Blessed are the peacemakers: for they shall be called the children of God."
