In 1956, with cynical timing French-Israeli forces launch an invasion of the Suez Canal just one hour after the polls close for the US Presidential election.
Conjoined Crisis Part 2
Suez Canal Invasion LaunchedUnbeknown to the International Community, the British Government had co-authored the Protocol of Sévres, a secret tripartite agreement that Israel would invade the Sinai. Britain and France would then intervene, purportedly to separate the warring Israeli and Egyptian forces, instructing both to withdraw to a distance of sixteen kilometres from either side of the canal. The reasons to desire to topple Nasser were various; for British Prime Minister Eden, ghosts of Munich, France, meddling in their colony of Algeria, and for Israel, collaborative opportunity to diminsh a local rival.
The rational voices in London and Paris argued that the Canal could not be held by force, and noted also that the modern oil tankers were becoming too big to travel through it. However, the debate was then transformed by a secret request for refuge at the British Embassy from Hungarian Premier Imre Nagy. The secret service urged Eden to betray Nagy and trade his liberty with a pledge of non-interference from the Soviet Union. But in the event, the British Government decided to grant refuge and withdraw from the Suez Canal, venture privately telling France and Israel that its position within the Commonwealth would become diplomatically untenable if London was seen to overtly support one head of state whilst seeking to oust another. However, as a sign of tacit support, London did allow the French to use Cyprus as a staging area and the operation proceeded without Britain.
