Mattei pushed hard for a line of detachment, of critical participation in NATO and even of getting out of NATO and into a neutralist position. Mattei therefore not only annoyed the United States with his oil deals in the Middle East, which broke up the balance of the international oil cartel, and broke up the price equilibrium, but it was Mattei who pushed even harder for Italy's entire policy to take its distance from the United States and to open up toward the Third World countries, which were traveling in a certain way along a road similar to the painful and laborious road which Italy had had to travel. Mattei was very sensitive to these problems, because he had been a witness to this difficult road of Italy's and had had great difficulties at the beginning of his career. So he knew what it meant for a country to free itself from the colonial yoke and find its own way, its own balance, and a way of arranging its own economy which would not be an economy of pure exploitation by the great powers (p. 23).
