In France, as Roy Jenkins rightly noted, “the reaction to Suez was quite different. There was less guilt and more anger. The lesson there learnt was never to trust the Americans and probably not the British either.
XREF: Plausibly connects to the broader narrative of post-1956 Anglo-American and Anglo-French relations that the surrounding work likely traces.
