Reuters reports that '10 Israeli soldiers were killed in a rocket attack.' Pretty much a random shot that could have gotten anybody outdoors. They were reservists, military age civilians about to become soldiers perhaps. On the other hand, I read of the soldiers coming back from Lebanon that there is a concern about using the Air Force against firing positions for Hizbullah. There may be women and children there, but they are not civilians. They are draftees. Of course I know that Jews have suffered, cf. my comments in Haaretz, as what I call draftees or what you may call hostages. You are not fighting an aggressive war which Leviticus prohibits. They like calling you Nazis, and you can favor or abjure thinking of yourselves as Panzergruppe Yishrael, but few of you are going to be given an opportunity for Argentina. There are military necessities.
An example of Israel's Rules of War.
"But is not the evaluation of a war in terms of its justice a practice of conscience?" Leon Wieseltier will take you, perhaps after registration, to some agreement and a window to why there is not 'proportionality' in sympathy to take up Nathalie's question from a previous post.
