first off it very well could happen and i'm not talking 10 or 15 terrorists. i live close to kinzua dam, i also live close to the national forge (makes bombs), i also live close to the united refinery (one of the largest fuel producing plants east of the mississippi.).... i can think of 101 ways that if a calculated attack were to occur, it would be devistating. i never once said that anybody would take over the united states.... i think i distinctly said small towns. i think that i distinctly said that we would overcome!! i am not a radical gun owner who stockpiles mass amounts of weapons and ammunition. i am a concerned citizen of the united states of america that worries that someday we will live in fear because of certain groups who want to take our second amendment right to bare arms away from us and leave us defenseless. did you ever think 9/11 could happen?? don't ever say never just look at the fall of the great roman empire.
