In 1956 the Suez Canal, previously owned by an Anglo-French company, was nationalised by the Egyptian government. The British and the French were both strongly committed to taking the canal back by force. President Eisenhower and the Soviet Union demanded there be no invasion and both imposed heavy pressure to reverse the invasion when it came. The relations between Britain and France were not entirely harmonious, as the French did not inform the British about the involvement of Israel until very close to the commencement of military operations. The failure in Suez convinced Paris it needed its own nuclear weapons.
