According to Osama bin Laden, the costs of Al-Qaeda to press the “9/11 Terrorist Attacks” button were in the region of $500,000. The USA responded by pressing hundreds of buttons. According to Joseph Stiglitz, the total costs associated to only one of them – the “Iraq War” button – were in the region of $3,000,000,000,000. I am not sure who are the next ones going bankrupt, but even with my eyes closed can point at those who have not learned their history lessons yet.
