How did European powers responded to great seizure of the Suez canal by?

Britain and France responded to the 1956 nationalisation of the Suez Canal by Egypt by launching a joint military operation, known as the Suez Crisis, in collusion with Israel. The crisis was sparked on 26 July 1956, when Egyptian President Gamal Abdel Nasser announced the nationalisation of the Suez Canal Company. This move angered the British and French, who saw it as a violation of the 1888 Constantinople Convention that guaranteed free passage of ships through the canal.

Britain and France's response was swift and decisive. On 29 October, they launched air strikes against Egyptian targets, and on 31 October, they landed troops in the Suez Canal Zone. The conflict lasted for six days, and resulted in a decisive victory for the British and French. However, the crisis also led to a significant loss of prestige for Britain and France, and marked the end of their colonial dominance in the Middle East.

The Suez Crisis also had a significant impact on the United States. President Dwight Eisenhower was opposed to the use of force by Britain and France, and he threatened to withdraw economic support from the two countries if they did not withdraw their troops. This pressure eventually forced Britain and France to back down, and they withdrew their troops from the Suez Canal Zone in late 1956.
