I fail to see how the execution of Stalinists in Yugoslavia during Informbiro could have been a carefully staged act between Stalin and Tito. I strongly suggest you read "Conversations with Stalin" by Milovan Djilas, a Yugoslav Politburo member who went from a hardcore Stalinist to anti-Stalinist and finally Yugoslav dissident.
As for Kosovo, Tito's right hand man, Aleksandar Rankovic (the Serb head of UDBA) ran the province as his own fiefdom for two decades. It was only after his removal for spying on Tito that the Albanians got into power in Kosovo.
Great Author. But his literary résumé may very well blend fact, fiction, and fantasy. I personally distrust newly-minted anti-communists who were fervent hard-line Marxists a short time before.
In re Kosovo: Review NYT early reportage. When Tito was in power, the Kosovar Albanians were given a great deal of autonomy, which they immediately misused to persecute Serbs, Jews, and the "Röm." At the time, the NYT thought this was absolutely horrible. Shocking to misuse the trust of Tito, one of their commie pets, etc. etc. etc. "Bandits," the NYT called them.
The minute Tito was dead and Serbia eventually became an internationally recognized state rather than part of communist Yugoslavia, these shocking Kosovar Albanian "bandits" suddenly became freedom fighters in the good grey pages of the NYT.
As to the execution of Stalinists during Informbiro, I seem to recall many earlier episodes of internecine bloodshed among Stalinists ... proves nothing. Remember also Tito's disgraceful persecution of Croatia's Cardinal Stepinac with manufactured KGB evidence, and many of the more outspoken Othodox prelates. Remember also that Tito, taking yet another Stalinist directive, sought to dominate the Serbian Orthodox Church.
No, I'll go with Golitsyn on this one. Perhaps it's personal, but Tito will never be a hero to me. THere are no angels in the Balkans, but Tito was definitely a bloody devil.
