In his contributions over the past week to the 9/11 25th anniversary discourse, Matt Yglesias has offered a fine synthesis of the chief strands of the emerging liberal nostalgia for Bush. Yglesias wants us to remember that, however many mistakes the U.S. made in its response to 9/11 (and he agrees there were many), the motive force behind the "War on Terror" was a genuine commitment to universal values.
Bush really meant it, in other words, when he said that stuff about advancing "freedom" and "democracy" around the world. Many neoconservative and even liberal and left intellectuals (Christopher Hitchens, e.g.) went along with it because they believed it too. The post-9/11 response, then, really was part of a larger commitment to "liberal cosmopolitanism" in that era, as Yglesias puts it.
