I don't see it quite like the way they describe, but there is probably some truth to that. The US wants Hezbollah weakend, sure, but if Isreal does something other than accomplish that, I don't think much will change in the eyes of the US.
The way I see it, Isreal is a sovereign nation and Hezbollah launching rockets into Isreal violates that sovereignity. THey must do what they must do to stop it, since its obvious Lebonon has little interest in doing anything about it, and so this is how the cards lay. They must insure their security at all costs because any other country would do the same.
If you question what Isreal is doing right now, then the US and other foreign nations have no right to be in Afganistan either, since they are there on the exact same grounds. Just a thought. Running out of time though, otherwise I'd go into more depth - got to get out of here in about 20 min -need to pick up something.
