Your memory of what you read about the 1967 war from a safe distance is not accurate. The debate in Israel was about whether a self-defence operation was possible, not whether it was necessary. Many believed that the international community would not allow Israel to defend itself and some also hoped that the USA and other countries would keep their promise to open the Straits of Tiran with their own ships. By 5 June 1967 it was clear that no other country would lift a finger to help Israel while a Soviet-backed Arab invasion was ready and expected to begin at any moment. As long as the oil supply through the Straits of Tiran remained closed Israel's capacity to resist the second Holocaust was draining away by the hour. That is why for the first time in Israeli history there was total unanimity in support of the decision taken by the national unity coalition government.
