On some basic level, you forfeit your right to be called civilians when you freely elect members of a terrorist organization as statesmen, invite them to dinner with blood on their hands and allow them to set up shop in your living room as their base of operations. At that point you begin to look a lot more like conscripted soldiers than innocent civilians. And you have wittingly made yourself targets.
For comparison’s sake, here’s Osama Bin Laden attempt to justify the Sept. 11 attacks:
[T]he 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."

També es podria aplicar un argument similar a l'11-M.
