The 1958 Middle East crisis led to a change in the relations between the United States and Israel. The Eisenhower administration looked at Israel as a strategic ally in a region that fell under the sway of the Soviet Union. Hesitantly, the seeds for strategic cooperation between the two nations were being sown. The deepening strategic ties between the two nations led the American recognition that the Arab–Israeli conflict was conflated with the Cold War. Consequently, the United States recognized that Israel needed arms in order to maintain its strength whilst facing an Arab military challenge due to the Soviet military support for the Arab states. In a gradual process that began with President Eisenhower and culminated with President Lyndon Johnson, the United States became Israel’s main arm supplier. The 1967 June War further deepened the attachment between the two nations. Evangelicals cherished what they saw as the fulfilment of the prophecies about the restoration of the Jewish state, and the American people and politicians viewed the Israeli victory as additional proof of the Israelis’ high spirit and capabilities, especially when compared to the failing war in Vietnam. For Israel, which came to control more territories, the war provided an additional opportunity to deliver its messages to the United States through tourism diplomacy. The war also forced Israel to contemplate its place in the Middle East, with peace becoming a more plausible option.

Religion, shared values, and history led American politicians to support the Zionist cause during the inter-war years. Presidents, politicians, and the American people supported the Zionist aspirations, although, it was only after the Second World War that the Americans became actively involved in Zionist affairs. During the inter-war years, the British government acted to fulfil the commitment it made in 1917 to help the Jews to establish a national home in Palestine. When the winds of war were blowing across Europe, the British began to back out of from the mandate and their commitments, and the Zionists turned to the United States for support. This marked a change in the Zionist attitude toward the United States – they wanted to see the United States extend its sponsorship of the Zionist enterprise. The ideological infrastructure for such a tutelage already existed; now the Zionists expected the Americans to act upon their ideology. During the war years, more promises were made than actions taken. However, when the war was over, and a new president, Harry S. Truman, occupied the White House, ideas inspired action, and President Truman acted to assist the Jews in attaining their goal of statehood.
