Al Qaeda and other so-called "radicalized Islamist groups" get most of the copy in the media. However, an equally dangerous and radical form of terrorism is the eco-terrorist. Groups such as the Earth Liberation Front (ELF) and Animal Liberation Front (ALF) use bombs and other forms of violence to draw attention to their issues.
ELF has set fires to log home mansions to call attention to the use of old growth timber in the construction of these homes.
Media reports have tied Theodore Kaczynski, also known as the Unabomber, to environmental activists, and say that the 23 injuries and three deaths through letter-bombs were the acts of an independent eco-terrorist.
Earth First! is found of driving railroad spikes (tree spiking) into old growth timber. When lumberjacks go to cut the trees, the spikes will shatter the chains of their chain saws causing gruesome injuries or death.
While most of these groups have focused on preserving the ecology or protecting animal rights, there has always been some groups opposed to nuclear energy. The crisis in Japan has apparently provided the impetus for these groups to turn to violence as well:
GENEVA -- A letter bomb has exploded at an office of the Swiss nuclear power industry in the northern city of Olten, injuring two people, police said Thursday.
The explosion happened shortly after 8 a.m. as staff were opening the morning's post in the fourth-floor office of Swissnuclear
The Unite States has 104 nuclear power plants. The Department of Energy and Department of Homeland Security will need to collaborate on how to best protect the workers as well as the facilities at these plants. We already know we have threats from Al Qaeda, and now probably Gadaffi as well, domestic terrorist groups (including eco-terrorists) and the Mexican drug cartels. The United States may not have to wait for a natural disaster to turn one of our nuclear power plants into the next Chernobyl.
