- 9/11 was terrible, but even if a 9/11 would happen each and every month, terrorism would still be less deadly to Americans than motor vehicle accidents. Seems almost silly to spend 10 years, thousands of lives, and trillions of dollars fighting this "threat". http://www.cdc.gov/nchs/data/nvsr/nvsr59/nvsr59_04.pdf 10 comments reddit.com
