I'm new here but it's an interesting and very difficult subject. Maybe I'm biting off more than I can chew by taking a different viewpoint. Let me start by saying I'm torn. And that I fully support Israel's "right to exist" and retaliate in any form they see fit, as Masashi outlined.
But since this thread is hardly going to change the world for the sake of argument let me carry the mantle for a moment for the Hezbollah (yech, I don't even like saying that).
With all due respect to continue the analogy....I think it was an Arab dog, that was taken long ago by Animal Control (maybe you adopted it at the pound) and the Arabs really want it back, and never wanted Animal Control to take it in the first place.
My take on Middle East history is that the Jewish had been leaving Israel for hundreds of years and losing a long battle for the area in 1947, when the UN stepped in and created dividing the nation into Arab and Jewish segments (essentially creating a civil war) .

The UN (and most recently the USA) has nearly always supported Israel in no small part as a sort of "payback" for the Holocaust, with which of course the Arabs had no role. The UN even went so far as to give a minority of the population (33%) the reigns of government for the newly created state, and gave the Arabs (67%) no role whatsoever in ‘self-determination.” Also those percentages of course don’t include the region (Syria, Lebanon, Iran, etc...etc…
In a sense the UN set up and continues to support a system not unlike Apartheid. I firmly believe that without that support and backing for the past 60 years Israel would have long ago left that bar or at least they would not have maintained “ownership” over the place.
Clearly some of the Arab leaders and nations have shown more “war-like” tendencies, they don’t seem to be “nice” peace loving people. I believe part of this is a result of the affronts mentioned above, a long history of conquests and tribalism, and a slow or non-existent adoption of diplomacy, and slower adoption of 20th century western concepts of peace.
Peace out
