The New York Times' online column brainstorming for ideas to kill Americans does point out a massive vulnerability for America -- the fact that during wartime, such a column was editorially acceptable and legal for public distribution.

The real question that Americans should be asking is WHY it is legal and editorially acceptable - not only for the Steven Levitt columns, but also for the Hezbollah and Hamas editorials. This goes back to the fundamental unresolved questions in the minds of a segment of the public as to: (a) is the USA at war or not, (b) if so, who is the enemy, (c) what is our war strategy against the enemy.
