Disproportionate Retaliation

With over 200 Australian's now trapped in Lebanon, and Israeli bombardments wiping out countless civilians to get at a few Hezbollah, I think that the Western world should intervene and stop Israel. A young Jewish Australian on TV last night came on critisizing Israel, and was debating an older Jewish man, defending the actions as 'security measures.' Although Hezbollah should have been disarmed by the Lebanese government, is attacking the roads and airports, stranding foreign civilians as well as killing many, ethically right? Surely not.
