Domestic politics are overshadowed by economic hardship resulting from the worst drought the country has ever experienced. The lack of rain over large areas in 1971 has decimated the sheep population, which constitute the principal source of protein for a meat-eating nation; food crops also suffered severely. The year 1972 brings little relief, and the flow of people into Pakistan and Iran in quest of food continues. Both these countries again respond generously to the government's appeal for external assistance, and later in the year United Nations agencies give substantial help. Even so, by the fall the situation in some provinces, particularly Ghor, becomes desperate. Some 50,000-100,000 people, many of them women and children, face starvation. At this juncture, the United Nations Children's Fund rushes food, medicine, and clothing to the distressed area, and many people who would otherwise have perished are kept alive. The king and his government work tirelessly to overcome the national emergency, but the country's resources are still limited, communication with many outlying regions is not easy, and effective relief work is handicapped by local traditions of autonomy. One bright spot is the growing importance of the tourism. Foreign travelers naturally follow the excellent roads, constructed mainly with Soviet Union and United States help, that link the major cities, and are little tempted to go beyond the direct overland route from Europe to India and Nepal, in which Afghanistan is an essential link. Thus they are little affected by the distress in the outlying areas, and the Foreign exchange market that they bring into the country proves invaluable to the government. In foreign affairs Afghanistan's traditional policy of Neutral country is strictly observed, and relations with all its neighbours remain friendly. No attempt is made to take advantage of Pakistan's difficulties, but, at the same time, economic and cultural contacts with India continue.
