You dont need to stop the stock market to destroy the economy. There are over 10 million people who live in or near Chicago and every single one of them, including me is packing up and leaving after the two weeks are up. Say goodbuy to companys like Motorola, Boeing, and countless others who are based near Chicago, whos employess are dead or gone, and their offices and plants are radioactive. Not to mention that cash is only worth cash if you believe that the US government supports the dollar. The first thing i do if their is a nuke attack in a US that i dont like in is go to the bank and take out every cent i can. (im 19 and a college student so its only like 4K). Losing 4 of the biggests cities would ruin the economy. We'd survive but many would starve because of transportation problems.
