The does not seem to be a complete text of the islamic Declaration on the internet, but the quotes that I cited are all over the place--on Serbian, Croatian, British, French, American, and other websites. You can get photcopies of the relevant pages (in "Serbo-Croatian") by contacting Peter Makara at http://www.srpska-mreza.com, if you don't mind getting them from a Serbian "disbeliever". The 1990 edition was published by Mala Muslimanska Biblioteka in Sarajevo, and tranlated into English and other languages. Several libraries that specialize in South Slavic materials also have copies, at least of the "Serbo-Croatian" edition.
As for whether there were islamic fundamentalists/supremacists in 1970--although there were none of the current wave of CIA-spawned jihadists, there have all throughout the history of islam been "fundamentalist" movements. Some well-known ones are the Almohads who conquered muslim Spain in the 12th century, and ended the "golden age" there, and the Madhist movement in Sudan in the 19th century.
More relevant are the 200-year-old Wahhabi movment in Saudi Arabia, and Khomeini and his movement, which was active in the West in the 1960s and 1970s, before taking power in Iran in 1979. Izetbegovic was in contact with at least the Iranians from an early time.
Izzie himself was part of another islamic supremacist movement in the 1940s, the Nazi/muslim movement founded by the Grand Mufti of Jerusalem, Haj Amin al-Husseini. The young Izzie fought for the Nazis in al-Husseini's thuggish Bosnian muslim units, and founded the Young Muslims (Mladi Muslimani) to carry on the islamic supremacist cause in Bosnia. The Young Muslims formed the core of Izzie's party, and of the "Bosnian" government, in the 1990s.
Their goal was always the formation of a "Bosnian" state--no matter how small--that could be dominated by muslims, and serve as a launching pad for the islamization of Europe. And it also became a base for attacks against America. The mirror image of Izzie's small Bosnia is of course Republika Srpska and probaly a Croat Herceg Bosna as well. The existence of these Christian ethnic enclaves is made necessary by Izzie's strategy, and is NOT the result of some mythical plot to create a "Greater Serbia"!!
As for Pakistan--its "secularism" has always been relative. Pakistan was created as a state for muslims who did not want to live together with Hindus and others in India. It is thus by design islamic supremacist. Pakistan has always had a legal system that is influenced by sharia, even when it has not fully implemented islamic law. (That is also true of many other islamic states such as Egypt.) Pakistan is far, far away in its laws, govenment, and customs from the only islamic country that is a secular state, Turkey. And it has always had an expansionist and warlike streak, which is now worse than ever!!!
