World War III? Israel & Co. vs. Lebanon & Co.

The history books might have to make some room for the next "great" war. This time, it might be the East vs. the West. As the escalation in attacks between Israel and Lebanon's Hezbollah continue, the possibility of an all-out war solidifies among the rest of the world. Hezbollah, a politically and military powerful organization in Lebanon (condemned as a terrorist organization by many Western countries, including the United States), begun the exchange by kidnapping two Israeli soldiers in a border raid. Now, Lebanon is dealing with the fallout of this incident, or, as Saudi Arabia has called it, this "uncalculated adventure".
Israel's Prime Minister Ehud Olmert has promised that this will no longer will be a tit-for-blown up tat, but that Israel will see this in us vs. them terms. Syria has been included in the "them" category, as Israel accuses them of supplying Hezbollah with newer, better rockets, the which they never possessed before recent attacks. Syria, then, has responded by saying that they will support Hezbollah to the fullest extent. The war is gradually surpassing local turmoil. Syria, along with a reluctant Saudi Arabia, is on Hezbollah's side, and, since there is no other choice for Lebanon's Prime Minister, Fouad Siniora, so is his country. Who, then, is on Israel's side? The Bush administration has not only failed to condemn the attacks by Israel, which range from destroying power plants to blowing up the Syria-Lebanon highway (both violations of international laws of war), but has tacitly endorsed furthering the attacks. Thereby, making the United States a possibly ally, or at the very least, not an obstacle to further escalation. The possibility that Saudi Arabia would join the Hezbollah-bloc, if only through finacial means, makes the conflict of the upmost importance.
Israel must now deal with the ultimate question: how many Israelis must be in danger until this becomes a World War? Alliances are being made, threats are materialized, consequences continue to increase. Who will stop their calls for war, Hezbollah or Israel? Someone needs to focus on reason rather than retribution.
