Today, President Barack Obama gives what has been billed as a major address on the status of the "war on terror," a term that the Obama administration doesn't use but that is still how we refer to the efforts the United States takes around the world fighting al-Qaeda, those affiliated with al-Qaeda, those who might be affiliated with someone who is affiliated with al-Qaeda, and pretty much any nongovernmental entity that looks at us funny.
Whatever you call it, the war on terror is our endless war, just as George W. Bush set it out to be. With a Congress and most of a public willing to let him do almost anything he wanted, Bush's administration told us all those years ago that we were fighting not al-Qaeda or even terrorism but "terror" itself. In other words, our war would be not against a group of people or even a tactic that anyone could use but against our own fear. And that's a war we can never win.
Nevertheless, when Barack Obama was running for president, you might have thought that five years into his presidency there wouldn't be much of a War on Terror left. Most visibly, he wanted to get us out of Iraq, then wrap up Afghanistan. Mission, well, sort of maybe eventually accomplished. But the War on Terror lives on, at our airports, in government budgets, and in our laws.
