Ever concerned with broadening his base of support among the diverse elements of Iraqi society and mobilizing mass support, he closely followed the administration of state welfare and development programs. At the center of this strategy was Iraq's oil. On 1 June 1972, Saddam oversaw the seizure of international oil interests, which, at the time, dominated the country's oil sector. A year later, world oil prices rose dramatically as a result of the 1973 energy crisis, and skyrocketing revenues enabled Saddam to expand his agenda. Within just a few years, Iraq was providing social services that were unprecedented among Middle Eastern countries. Saddam established and controlled the "National Campaign for the Eradication of Illiteracy" and the campaign for "Compulsory Free Education in Iraq," and largely under his auspices, the government established universal free schooling up to the highest education levels; hundreds of thousands learned to read in the years following the initiation of the program. The government also supported families of soldiers, granted free hospitalization to everyone, and gave subsidies to farmers. Iraq created one of the most modernized public-health systems in the Middle East, earning Saddam an award from the United Nations Educational, Scientific and Cultural Organization (UNESCO). With the help of increasing oil revenues, Saddam diversified the largely oil-based Iraqi economy. Saddam implemented a national infrastructure campaign that made great progress in building roads, promoting mining, and developing other industries. The campaign helped Iraq's energy industries. Electricity was brought to nearly every city in Iraq, and many outlying areas. Before the 1970s, most of Iraq's people lived in the countryside and roughly two-thirds were peasants. This number would decrease quickly during the 1970s as global oil prices helped revenues to rise from less than a half billion dollars to tens of billions of dollars and the country invested into industrial expansion. The oil revenue benefited Saddam politically. According to "The Economist", "Much as Adolf Hitler won early praise for galvanising German industry, ending mass unemployment and building autobahns, Saddam earned admiration abroad for his deeds. He had a good instinct for what the "Arab street" demanded, following the decline in Egyptian leadership brought about by the trauma of Israel's six-day victory in the 1967 war, the death of the pan-Arabist hero, Gamal Abdul Nasser, in 1970, and the "traitorous" drive by his successor, Anwar Sadat, to sue for peace with the Jewish state. Saddam's self-aggrandising propaganda, with himself posing as the defender of Arabism against Jewish or Persian intruders, was heavy-handed, but consistent as a drumbeat.
