Short answer: It's called self-defense, which is legal under international law.
In your Question, why do you mention only one side of events?
Like some of the media, the U.N. and others, you may be biased.
What about the thousands of Israelis that have been killed by Palestinian terrorists?
What about the fact that Palestinians walk in Jewish neighborhoods without fear, while no Israeli dares enter many Palestinian areas, for fear of car-theft and lynching?
What about the fact that in forming the State of Israel as permitted by the U.N., the nascent State was attacked by seven foreign armies and survived only by the grace of God? Was Israel fighting a one-sided war?
How did the Middle Eastern terrorists justify blowing up public buses, schoolchildren, restaurants, etc., tens if not hundreds of times in recent decades?
Israel holds itself to a higher standard. Every Israeli soldier is taught again and again about the Rules of Engagement. Israel targets a few MILITARY objectives after tens of missiles deliberately hit CIVILIAN houses in Israel, and much of the international media twist the story into the opposite. Israel does the minimum for survival, contorting itself in its efforts to avoid killing non-combatants, but is viciously denounced when there are collateral deaths.
Israel's enemies could lay down their weapons, and ask us directly: "Why hasn't Israel returned to its pre-1967 borders"? Then we could carry on a serious debate. And that issue is not one-sided.
No. It is very rare, but the probability increases if you talking about Arab Israelis and Palestinians (as opposed to Jewish Israelis and Palestinians).

The Israelis and Palestinians are fighting over a small piece of land called the Gaza Strip and the West Bank.The Israelis and Palestinians are fighting about a wide variety of things. Please see the Related Question to read more about the conflict.
There is an ethnic and national conflict between Israelis and Palestinians and therefore there are several cases of Israeli Security Forces torturing Palestinians. Additionally, a number of the laws used in the Occupied Territories are subject only to Israeli Military Review which prevents Civil Law from taking action to prevent such abuses. However, it is incorrect to assume that all Israelis or even most Israelis torture Palestinians.
Peaceful co-existence.
It began with the religious conflicts where Palestinians were not ready for peace.
Yes. There are land disputes between Israelis and Palestinians and the land in dispute is located in Southwest Asia.
The West Bank
Yes, they do. See the related question on why that might be.
No. Neither of them are fighting "the Muslims" as a group. Most Palestinians are Muslims anyway. The Israeli-Palestinian Conflict is between two national groups: Israelis who are primarily Jewish against Palestinians who are primarily Muslim. However, neither Israeli nor Palestinian forces have declared that they are fighting Islam. There are numerous mosques in both countries where Muslim worshipers freely pray to God.
