You're right that most Americans don't care about this and, to the extent they do the pro-Israel group has more resources and have it as a higher political priority. On the other hand the pentagon and state dept definitely see it as a security issue. They see a highly militarized Israel as an asset as a detterent and an insurance policy if things pop off in the ME. This is the conventional wisdom, but it's far from controversial if it's the best policy given that Arab forces refuse to fight on the same side as the Israelis, and modern US war stategy calls for using local indigenous forces they prop up. Overall the US will never except not having a strong military presence in the ME (atleast until oil demand drops in the coming decades when renewables become very cheap) and Israel is one of the ways they achieve this.
Edit: for some reason I said far from controversial, but I meant it is controversial.
For now, pretty much unfortunately. Once oil demand drops the ME will be less of a priority for the US, but then will have to contend with the Israel lobby which won't go down easy.
