However, by 1975, Mohammad Reza had abolished the two-party system of government in favour of a one-party state under the Rastakhiz ("Resurrection") Party. This was the merger of the New Iran Party, a centre-right party, and the People's Party, a liberal party. The Shah justified his actions by declaring: "We must straighten out Iranians' ranks. To do so, we divide them into two categories: those who believe in Monarchy, the constitution and the Six Bahman Revolution and those who don't ... A person who does not enter the new political party and does not believe in the three cardinal principles will have only two choices. He is either an individual who belongs to an illegal organisation, or is related to the outlawed Tudeh Party, or in other words a traitor. Such an individual belongs to an Iranian prison, or if he desires he can leave the country tomorrow, without even paying exit fees; he can go anywhere he likes, because he is not Iranian, he has no nation, and his activities are illegal and punishable according to the law." In addition, the Shah had decreed that all Iranian citizens and the few remaining political parties become part of Rastakhiz. From 1973 onward, Mohammad Reza had proclaimed his aim as that of the "tamaddon-e-bozorg", the "Great Civilisation," a turning point not only in Iran's history, but also the history of the entire world, a claim that was taken seriously for a time in the West. On 2 December 1974, "The New Yorker" published an article by Paul Erdman that was a conjectural future history entitled "The Oil War of 1976: How The Shah Won the World: The World as We Knew It Came to an End When the Shah Of Iran Decided to Restore The Glory of Ancient Persia with Western Arms". In 1975, U.S. Vice President Nelson Rockefeller declared in a speech: "We must take His Imperial Majesty to the United States for a couple of years so that he can teach us how to run a country." In 1976, a pulp novel by Alan Williams was published in the United States under the title "A Bullet for the Shah: All They Had To Do Was Kill the World's Most Powerful Man", whose sub-title reveals much about how the American people viewed the Shah at the time (the original British title was the more prosaic "Shah-Mak"). The great wealth generated by Iran's oil encouraged a sense of nationalism at the Imperial Court.
