Despite our reputation, most Americans can take criticism about our country. But if there's one touchy subject, it tends to be 9/11. We're still understandably upset about that.

That's why Americans are up in arms about comments made by Oxford University's incoming vice-chancellor Louise Richardson. At a British Council panel debate in London, she said that the United States' response to the 9/11 attacks was an "overreaction," and that the British people would have reacted more appropriately because of their "resiliency."

Complicating this story is the fact that Professor Richardson is one of the leading terrorism experts in the world. A native of Ireland, she grew up during the infamous "Troubles" that claimed 3,600 lives there over the course of 30 years. She taught at Harvard for 20 years before become the vice-chancellor of St. Andrews University in Scotland in 2009. She is the author of What Terrorists Want: Understanding the Enemy Containing the Threat, and regularly advises world governments on issues related to terrorism. She has also testified as an expert before the US Senate.
