So Israel has decided to treat the latest act of war by Hezbollah as, by gum, an act in a war, and is fighting a war in return. Israel's ambassador to Washington is also talking very tough about Iran's part in Hezbollah's activities.
I wonder if this is as much about how to solve the problem of Iran-about-to-have-nukes as about Hezbollah. Perhaps Israel has been biding its time, waiting for Iran's interference in Lebanon to become blatant enough that (a) there'd be sufficient provocation to go into Lebanon and (b) attacking Iran would be a logical next step. If Iran's nuclear program wasn't sufficient casus belli, now Israel has a better one.
