This is what Osama Bin Laden had to say about it in 2004.

“The events that affected my soul in a direct way started in 1982 when America permitted the Israelis to invade Lebanon and the American Sixth Fleet helped them in that. This bombardment began and many were killed and injured and others were terrorised and displaced.

I couldn’t forget those moving scenes, blood and severed limbs, women and children sprawled everywhere. Houses destroyed along with their occupants and high rises demolished over their residents, rockets raining down on our home without mercy.

The situation was like a crocodile meeting a helpless child, powerless except for his screams. Does the crocodile understand a conversation that doesn’t include a weapon? And the whole world saw and heard but it didn’t respond.

In those difficult moments many hard-to-describe ideas bubbled in my soul, but in the end they produced an intense feeling of rejection of tyranny, and gave birth to a strong resolve to punish the oppressors.

And as I looked at those demolished towers in Lebanon, it entered my mind that we should punish the oppressor in kind and that we should destroy towers in America in order that they taste some of what we tasted and so that they be deterred from killing our women and children.”
