It's no secret that the US military is spraying depleted uranium all over the middle east, A war crime in itself, rendering hundreds of square miles of land uninhabitable for centuries. With the indescriminate use of such toxic substances, the depleted uranium supplies for our "enemies" is vurtually unlimited. All they have to do is scoop up a bucket full of contaminated dirt (sand?) go to Washington D.C. and sprinkle it around. Or if they're creative, Buy a plane, fill it with dirty sand and fly it into the white house. A dirty bomb would be all it takes to shut down the government for awhile. How would they get it into the US you ask? They already have. Our -resident, who's job it is to protect our borders from invasion, couldn't be doing a worse job of protecting anything. In fact, he purposfully lets the invasion continue, plus provides incentive. If they can smuggle tons of drugs through the border, a bucket of sand is nothing. And guess what happens to OUR liberty, and freedoms? Concider flying, with all the wasted money on TSA, and "airport security", what legitimate terrorist is going to try to use planes any more? Especially when they can walk over the border any time they want to. Thanks a lot obozo.
