Suez recast the Anglo-American relationship

How seriously did the Suez Crisis damage relations between Britain and the United States?

It fundamentally recast the relationship, replacing assumptions of equality with the language of a special friendship and influence beyond Britain's weight.

The crisis changed how Britain framed its position beside the United States. Before Suez, British leaders could still imagine an Anglo-American partnership of equals despite the altered balance of power after the Second World War. The language of a special friendship offered a new way to preserve access and influence without sustaining that claim of equality. Britain could keep trying to punch above its material weight while describing the asymmetry as exceptional closeness rather than simple dependence.
