Shmuel rebutted the argument that the Arab birthrate was cause for concern in the 1971 pamphlet, “Will Appeasement Lead to Peace”, which he co-wrote with former Mapai Knesset Member Eliezer Livneh:
Already in the three years after 1967 the Jewish birthrate in Israel rose by 20 percent and it is still rising, thus narrowing the gap. Moreover, it is likely that Arab emigration — a striking feature of the nineteen years of Jordanian rule — will continue. At the same time there has been a sharp rise in Jewish immigration, the numbers are rising from year to year, and there are more candidates for immigration than Israel is at present capable of coping with — a condition, however, which is improving.
The net result of the operation of these factors since 1967 is that the numerical preponderance of the Jewish population has increased. In 1967 the ratio of Jews to non-Jews (Arabs, Druzes, and others) throughout the territory held by Israel was 63.2 per cent to 36.8 per cent. Today [early 1971] the ratio is 66 percent to 34 percent. There is no doubt that the Jewish people has the necessary resources, spiritual and material, to meet the challenge of the Arab natural increase.
Shmuel’s predictions over 40 years ago are borne out today. As former Israeli Ambassador Yoram Ettinger, perhaps the leading voice against the demographic doomsayers, writes recently, “In 2013, in sharp contrast with projections issued by the demographic establishment, there is a 66 percent Jewish majority (6.3 million Jews) in the combined area of Judea, Samaria (1.66 million Arabs) and pre-1967 Israel (1.65 million Arabs), compared with a 40 percent Jewish minority in 1948 and a 9 percent Jewish minority in 1900.“
