It's time we calm down and fight terror with antiterror. This does not mean that we simply roll over and accept terrorism. There are things our government can and should do to fight terrorism, most of them involving intelligence and investigation -- and not focusing on specific plots.
But our job is to remain steadfast in the face of terror, to refuse to be terrorized. Our job is to not panic every time two Muslims stand together checking their watches.
I'll also note that those Americans who reacted to the 9/11 attacks by becoming virulently anti-Muslim have granted Osama his dearest wish.
