Ustaše
Vjekoslav Luburić helped form an organization called the "Croatian National Resistance" (Hrvatski narodni odpor). This became the most violent of the Ustaše organizations which were born after the WWII. Luburić commanded the organization for twenty-five years from his refuge in Spain. His organization was heavily involved in racketeering, attempted murder, extortion, hijacking, terrorist bombings, and other violent crimes. After his death, his successors on the organization commanding post sought out criminal organization ties with La Cosa Nostra, the Provisional IRA, and the Croatian Mafia in San Pedro. Odpor was banned in Germany for terrorist activities and operated (in the US and Canada) between legitimate emigre functions and a thuggish underworld. Its leaders tried to distance the organization from the acts of the so-called renegade elements that hijacked international flights and served prison sentences for extortion. Odpor embraced a radical nationalist ideology that differed only marginally from Ustaše ideology.
