No, Israel has never lost to Lebanon - or any or all of the surrounding Arab/Muslim nations. Israel agreed to stop fighting on the basis of UN promises to police the area and assure that all PLO and Hezbollah fighters and arms would be removed from Lebanon. The UN has not followed through on those promises and the elements that were supposed to be removed have continued to commit acts of war against Israel. Seems the rules do not apply to anyone but Israel, which is supposed to just sit still and take it! Seems like racial/ethnic prejudice to me!
