On December 7, 1941, Japanese war planes bombed the U.S. naval base at Pearl Harbor, Hawaii. Six decades later, Al Qaeda terrorists flew hijacked airplanes into the World Trade Center and the Pentagon. Neither President Franklin Roosevelt nor President George W. Bush targeted and killed Americans on U.S. soil in the aftermath of those attacks. Doing so wouldn't have made any sense. How strange, then, that Attorney General Eric Holder invoked those very attacks in a letter confirming that President Obama believes there are circumstances in which he could order Americans targeted and killed on U.S. soil. "It is possible ... for the President to authorize the military to use lethal force within the territory of the United States," he wrote. "The President could conceivably have no choice but to authorize the military to use such force if necessary to protect the homeland in the circumstances of a catastrophic attack like the ones suffered on December 7, 1941 and on September 11, 2001." The very scenario to be guarded against is a president using the pretext of a terrorist attack to seize extraordinary powers. Isn't that among the most likely scenarios for the United States turning into an authoritarian security state?
