Osama bin Laden on why targeting civilians in the 9/11 attacks was justified

You may then dispute that all the above does not justify aggression against civilians, for crimes they did not commit and offenses in which they did not partake: 

This argument contradicts your continuous repetition that America is the land of freedom, and its leaders in this world.  Therefore, the American people are the ones who choose their government by way of their own free will; a choice which stems from their agreement to its policies.  Thus the American people have chosen, consented to, and affirmed their support for the Israeli oppression of the Palestinians, the occupation and usurpation of their land, and its continuous killing, torture, punishment and expulsion of the Palestinians.  The American people have the ability and choice to refuse the policies of their Government and even to change it if they want.

~ Osama bin Laden, "Letter to the American People," November 2002
