The Canal and Britain’s Far East Lifeline

Why did Suez matter so much to Britain's apparent postwar recovery and global role?

It was the fast reinforcement route to Asian wars and Commonwealth commitments, so losing reliable access undermined Britain's ability to act globally.

British troops, aircraft, and supplies had travelled through Suez toward the Korean War. The same route underpinned promises to support Australia, New Zealand, Ceylon, and other positions east of the canal, while France depended on it for access to Indochina. Going around Africa would slow reinforcement and demand a much larger support network. London and Paris therefore treated control of Suez as a strategic lifeline even when Nasser viewed nationalisation primarily as an Egyptian political and economic project.
