Wrong, and wrong.
Sure, there are people who are interested in supporting Israel for non America-centric reasons. I'm not claiming that's untrue, I'm claiming that is not the only reason. The fact that some people have other motivations does not change the fact that there is strategic utility in having them as an ally. They're a check on Iran, Egypt, and Turkey, all of whom have the potential restrict critical naval shipping lanes. They also give us an (even) stronger hand in our relationship with the Saudis, because if they piss us off enough, we don't need them to have basing and military support in the region.
