Suez without American intervention

If the United States stayed out of the Suez Crisis and Britain retained more naval capacity plus Commonwealth support, how might global roles change?

Absent wider Soviet escalation, the Anglo-French Mediterranean force could dominate the Soviet Black Sea Fleet and a stronger Commonwealth might remain a Western burden-sharing power.

The immediate naval balance and the danger of a general European war point in different directions. Soviet intervention could widen the Suez Crisis into a land war in Europe, giving Washington a reason to intervene even though Britain and France held the stronger Mediterranean fleet. In a contained naval fight, the modern Royal Navy and Marine Nationale forces deployed there greatly outmatched the Soviet Black Sea Fleet. Their carrier aviation and concentration of capable ships could make the clash short and severe. Over time, Britain and the Commonwealth might remain a distinct Western power that shared more of the security burden without matching the United States.
