Weren't they already at war?

Seems Hezbollah has vowed 'open war' with Israel over its putative slaying, via car bomb, of their boy Imad Mughniyeh.

Rico never noticed that Hezbollah had declared peace with Israel, so he's not sure what's different now. But Israel, never a slouch when it comes to threats, "ordered its military, embassies and Jewish institutions overseas to go on alert". But, no matter who killed Mughniyeh, it's a good thing: "We've had a vested interest in seeing this guy dead since he took 241 Marines from us in 1983, a Navy diver in 1985, and 19 soldiers and airmen in 1996. Bob Baer, a career spook with ops time in Lebanon, called him the 'grail' that we've been after for over two decades."

Rico says a car bomb is the best thing Imad could have hoped for...
