The United States needs to be concerned about terrorism to prevent tragedies like 9/11 from happening again, to address problems with domestic terrorism, and to improve homeland security....
It's not true that no one worries about terrorists attacking chemical plants. It's just that our politics seem to leave us unable to deal with the threat. Toxins such as ammonia, chlorine, propane and flammable mixtures are being produced or stored as a result of legitimate industrial processes. Chlorine gas is particularly toxic; in addition to bombing a plant, someone could hijack a chlorine truck or blow up a railcar.
The World Trade Center Demolition and the So-Called War on Terrorism
Since 9/11, we've spent hundreds of billions of dollars defending ourselves from terrorist attacks. Stories about the ineffectiveness of many of these security measures are common, but less so are discussions of why they are so ineffective. In short: Much of our country's counterterrorism security spending is not designed to protect us from the terrorists, but instead to protect our public officials from criticism when another attack occurs.
