Very brief history of Lebanese-Israeli conflict
You may have seen this in one of the morning papers but there's an AP write-up on the history of the Lebanese-Israeli conflict. It's a very brief article but worth the read if you're just looking for the basics. One quick fact from the article:
Because Israel and Lebanon have never signed a peace accord, the countries remain officially in a state of war that has existed since 1948 when Lebanon joined other Arab nations against the newly formed Jewish state.
