The US was motivated not to recognize it because of the Israeli diaspora in America. There isn't much of an "Israeli diaspora" to speak of the the U.S. At most it makes up 2-3 percent of the Jewish descendant (or identified) population. "Pro-Israel sentiment in Congress; more specifically, a sentiment favoring the current political status quo in Israel in regard to this particular issue" would be a better description of the proximate cause behind the current US policy, here.
