In December 2002, Ruebner published an article in CounterPunch describing the terrorist attacks targeting the United States as results of the United States' support for Israel. Ruebner called for a change in U.S. policy asking: "How many more Twin Towers need to fall before we realize that there are indeed consequences of the action (or inaction) that our democratically elected government takes in our name?"
