Why does the US support Israel so much; Are Americans really informed on the history of this?

When i look at he state of the middle east and all its chaos, I can't understand why the US gov and Americans support Israel so much. Now a lot of people say its because they are our only democratic ally in the region, but i want a deeper and meaningful explanation than this. Personally i feel it has to do with religion and Americans being uninformed. Take a look back at the history of that area, the formation of Israel has to do with Zionism and British Mandate in which basically the Palestinians had their land stripped from them. Which seems to be some what colonial. The general worldly view of the Palestinians is very negative because of there lack of recognition and aggression towards Israel. However Israel kills several fold more Palestinians than Palestine to Israel. A lot of the world won't recognize Palestine as a country because if their refusal to recognize Israel right to exist. However I sympathize with the Palestinians because of the history of that region and its land being taken away. As an example its almost but not completely similar to the Native Americans and other indigenous people having there land stolen because of European Colonial and Expansionism; Lol and we justify their retaliatory actions. I also feel that Islam has such a negative view in society because it has been manipulated to advance peoples Nationalistic agendas. So yeah I'm done rambling any thoughts?
