I suppose orthodox Anglospherists would object to the inclusion of, say, Bolivia and Nicaragua into the concept, but I am not so sure. If we take as our definition that given by James C. Bennett, Goldwater's "Atlantic Civilization" seems a nice fit with Anglospheric thought. Here is what Bennett said:

"The Anglosphere, as a network civilization without a corresponding political form, has necessarily imprecise boundaries. Geographically, the densest nodes of the Anglosphere are found in the United States and the United Kingdom, while Anglophone regions of Canada, Australia, New Zealand, Ireland, and South Africa are powerful and populous outliers. The educated English-speaking populations of the Caribbean, Oceania, Africa and India constitute the Anglosphere's frontiers."

Certainly this is broad enough in principle to emcompass Goldwater's vision? This "network civilization" (akin to Goldwater's American pillared "Atlantic civilization") is united by a web of political, economic, historical, religious, and linguistic realities, "galvanizing and guiding emergent nations everywhere" to use Goldwater's phrase.

It is one thing to be a prophet or a seer, it is another to be prescient and envision the future from current trends. I claim the latter for Barry.
