Is Israel preparing to strike Iran?

Perhaps, says The Washington Times, which is reporting this:

Israel has appointed a top general to oversee a war against Iran, prompting speculation that it is preparing for possible military action against Tehran's nuclear program.

Maj. Gen. Elyezer Shkedy, Israel's air force chief, will be overall commander for the "Iran front," military sources told the London Sunday Telegraph.

This may* mean nothing more than prudent preparedness. But what's wrong with that? After all, we all know what Iranian President Ahmadinejad thinks of Israel and how Iran supports Hezbollah.

Right?

(* If Israel really is preparing for an imminent strike, well, my preliminary view is that any such strike ought to wait for serious diplomatic efforts to run their course -- successfully, one hopes.)
