So it as some risk of filial impiety that I point you to Brad Delong's pointing to the New Republic Online's headline for a piece by Michael B. Oren:
To prevent a regional conflagration, Israel should attack Syria
As Professor Delong remarks, "Teh funny."
Read the whole thing.
Update: Matthew Shugart points out in the comments that even the Israeli left supports a limited reprisal against military targets in Syria as a more proportionate response to Hezbollah's abduction of the soldiers. That seems like a reasonable approach if, as seems likely, Syria is behind Hezbollah's actions. I have to admit to a blogging sin in that I didn't read the Oren article, but just the DeLong post, and if that is what Oren is proposing, then I apologize.
Update 2: Well, I read the piece and I shoulda listened to my pappy. Oren proposes taking out a 500 tank armoured unit in Syria. Whether this is feasible and sensible is beyond even my Internet-rules expertise to say, but it obviously does not deserve the snark DeLong and then the Pithlord engaged in. I'll leave this post up as a lesson in not following through on the links.
Update2: Here is Michael Walzer on what Israel can and can't do within the scope of just war theory.
