Why Britain misread Eisenhower during the Suez Crisis

How did Anthony Eden's government misread Eisenhower's likely reaction to Suez?

It treated him as the familiar allied general of 1944 rather than the American president of a changed Cold War world.

Personal familiarity with Eisenhower encouraged British and French leaders to use the wrong analogy. They remembered the allied general who had worked with them during the Second World War. As president, Eisenhower faced a different Cold War setting and American domestic political constraints that changed his incentives. Leaders who begin believing their own rhetoric can miss how far the political world and an old partner's responsibilities have changed.
