I would say that a big reason that the I side simply because they fought to craete their country out of nothing, and they are ally to the United States. The Hebrew peoples had no country to call home, thus Israel was fought for and created. They even won the 7 days war where many middle eastern nations declared war and attempted to attack them at once. This is also including the fact they are a strong United States position in the middle east. Although Palestinians have no home, they quite clearly lost in the fight to hold their lands, so why should they get it back for free.
