“Who controls the food supply controls the people; who controls the energy can control whole continents; who controls money can control the world” — Henry Kissinger
Publications either fail to reference their source, or give secondary references, or give incorrect references.
For an example of the last, https://ccp.org.au/content/2-exhibitions/1-all/0-fertile-gro... cites "Kissinger, H., National Security Council. (1974). The Kissinger Report: NSSM-200 Implications of Worldwide Population Growth for U.S. Security Interests", but I could not find that quote in https://pdf.usaid.gov/pdf_docs/PCAAB500.pdf .
I looked at that one because Google Scholar says that "Fertile Ground" document I linked to is from 1992. Internal evidence shows it's no older than 2019.
The oldest actual mention in Google Scholar is from 2006 at http://www.libertydollar.org/news-stories/pdfs/1161050727.pd... , without attribution. Note that https://mediabiasfactcheck.com/global-research/ refers to the organization as 'a Canadian conspiracy website'.
In 2007 there are a few more citations, like http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.532... . That in turn cites WikiQuote. WikiQuote currently has that quote in the Talk page under "None of these quotes should be reinstated in the article unless a source is found."
I looked at the next few years of publications which use that quote. None give a primary reference or even provide a citation.
This pattern strongly suggests that Kissinger did not say it. Clearly it must have been Lincoln or Churchill. /s
