Although the Department of State continues to attribute the war in Vietnam to “aggression from the North,” there has always been a suspicion among more enlightened public officials and most academic critics of the war that economic discontent rooted in the inequitable tenure arrangements of the Vietnamese countryside might have some connection with the vigorous opposition of the Viet Cong to numerous Saigon governments. Thus it is surprising to learn that, on the contrary, support for the Saigon regime is most pronounced in provinces in which few peasants farm their own land, large estates were formerly owned by French or Vietnamese landlords, tenancy is widespread, and the distribution of land is unequal. This finding is particularly striking since it is contrary to data from the rest of Southeast Asia. In Burma, for example dacoity and other forms of social disorder were most frequent in the deltaic area of lower Burma, a region of extensive tenancy, unstable tenure, massive agricultural debt, and large-scale absentee ownership by Indian financial houses. In Thailand most social tension is concentrated in the northeast, a region of poor soil and shifting subsistence agriculture, and in the Menam delta immediately adjacent to Bangkok, where absentee holdings are farmed by tenants. Most commercial agricultural land in Thailand is cultivated by owner-proprietors and it is this fact that explains much of the country's political stability. In the Philippines the Hukbalahap movement was concentrated in central Luzon, again a region of extensive tenancy.
