Today's Israeli-Palestinian conflict dates back thousands of years and combines politics, religion, race, war, and territory all in one.
If you really want to understand this from a non- biased point of view, your best bet is probably wikipedia, where different people with different viewpoints can debate the facts and non-biased writing is somewhat enforced.
The truth is that it's a very complex conflict with innocent people and some very shitty people, on both sides.
