Whats the real reason for USA's support of Israel?

Whats the real reason they're supporting these child killers? There've got to be one reasonable reason. Plz dont tell me the terrorist thing, Hamas didnt kill 75 children and 21 women in 9 days. Count numbers of dead bodies caused by arabs and those caused by Americans/Israelis/European and you'll know who are the terrorists. Anyway, i believe its because no one wants jews around so they are supporting them in middle east to make them stay there, if they really wanted israelis they would have given them a state in israel. What made me ask this question is because i just on tv a history of brutality and child killing from 1995 till now, and the vetoed resolutions against Israelis. I swear a tear just poured of me. When you see the real macres, they were beating a kid, a kid probably 8 year old, 6 soldiers beating him. And they were beating a naked man. And Americans in abo ghreib posing with happy faces with dead naked bodies of iraqis and women posing with them, this is brutality no religion accepts that. I still cant believe how do they call people who are beating slavered and widowed and orphaned terrorists. People throwing rocks against people with heavy armour and weapons and machine guns. Its sad. And why does USA support israel? Its the only country doing it. They care about animals and gay rights and complete non sense and not care about this. Dont they have hearts? Dont they watch tv? They're supporting it because few stupid short-ranged rockets hurts their feeling? God be with them against the real terrorists, i mean fellow palestinian heroes
