To give you the history of it, wouls take to long, you'll get it if you google it.
In a nutshell, the Palestinians and Hezbollah, backed by Syria and Iran, want to destroy Israel, its on their mandate.
This present trouble was caused first by Hamas kidnapping an Israeli soldier, and then Hezbollah kidnapping two Israeli soldiers, while at the same time, firing a rocket into Israel.
Israel has basically said, enough is enough, and wants to destroy Hezbollah, virtually an impossible task, and while i'm on the side of Israel, and can understan their initiaI reaction, I believe they've gone well over the top this time.
