(Source)The turning point in American policy on these issues was, incongruously, Richard Nixon, who is rarely praised or remembered for it (except at his own memorial foundation); however, one might surmise that it wasn't a coincidence that Nixon had witnessed the nadir of "terminationism" as vice-president to Eisenhower (HCR-108 was passed in Eisenhower's first year in office).
