A new enemy?

Justice Clarence Thomas wrote a strongly worded dissent from Thursday's ruling and took the unusual step of reading part of it from the bench — something he had never done before in his 15 years. He said the court's decision would "sorely hamper the president's ability to confront and defeat a new and deadly enemy."

But there is nothing new about Terrorism

"Modern Terrorism: The beginnings of modern terrorism may go back to the mid 19th century when a Italian revolutionary, Carlo Pisacane theorized that terrorism could deliver a message to an audience and draw attention to and support for a cause. Examples of early modern terrorism are the Klu Klux Klan, which formed to try to dissuade reconstructionists after the Civil War, and the Young Bosnians, which had Archduke Franz Ferdinand assassinated in Sarajevo in 1914, leading directly to the outbreak of World War One. It wasn't, however, until the 1960's that terrorism as we know it today came into prominence. The Palestine Liberation Organization (PLO), The Provisional Irish Republican Army (IRA), and other terrorist groups used attacks against civilian populations in an attempt to effect change for religious or ideological reasons. The most infamous incident of that time period occurred during the 1972 Summer Olympics in Munich, when a Palestine terrorist organization held eleven Israeli athletes hostage, who were then killed along with the terrorists during a rescue attempt."
