“Just like communism itself, Nikola Kavaja remains a controversial topic in the Serbian history,” writes Viktor Markovic of Belgraded.com about the man who made several unsuccessful attempts to eliminate Yugoslavia's leader Josip Broz Tito, including a 1979 hijacking of a U.S. passenger jet with the intention of crashing it into the Communist Party headquarters. Kavaja, 76, died in Belgrade earlier this week.
