Which countries refused to participate in the 1956 Olympics due to the Franco-British Suez Intervention?

The countries that refused to participate in the 1956 Olympics due to the Franco-British intervention in Egypt during the Suez Crisis were Egypt, Lebanon, and Iraq. This intervention was a significant geopolitical event in which Britain and France attempted to regain control over the Suez Canal after its nationalization by Egypt's President Nasser. As a reaction to this military action and to express their opposition, Egypt, along with Lebanon and Iraq, chose not to compete in the Olympic Games held in Melbourne, Australia. Their withdrawal was a political statement against the actions taken by France and Britain.

The choices of other countries like China, Japan, India, the USA, Canada, Brazil, Germany, Italy, and Spain do not align with the context of the Suez Crisis. Neither Japan nor India was involved in a protest linked to the Suez intervention, while the USA and its allies boycotted the Olympics in other contexts, but not specifically due to the Suez Crisis. Likewise, Germany, Italy, and Spain had different historical and political circumstances influencing their participation in international events during that period.
