Many excellent columns were written after 9/11/2001, but my favorite remains "When Innocents are the Enemy" by the late Michael Kelly.
The column is filled with many excellent observations, but the best is:
I don't doubt Arafat's shock. And I don't think he had anything directly to do with the monstrous evil of Sept. 11. Indeed, it is possible that what happened yesterday had nothing to do with the Middle East. But this evil rose, with hideous logic, directly from the philosophy that the leaders and supporters of the Palestinian cause have long embraced and still embrace -- a philosophy that accepts the murder of innocents as a legitimate expression of a legitimate struggle.If it is morally acceptable to murder, in the name of a necessary blow for freedom, a woman on a Tel Aviv street, or to blow up a disco full of teenagers, or to bomb a family restaurant -- then it must be morally acceptable to drive two jetliners into a place where 50,000 people work. In moral logic, what is the difference? If the murder of innocent people is for whatever reason excusable, it is excusable; if it is legitimate, it is legitimate. If acceptable on a small scale, so too on a grand.
