I didn't read much of the site yet, but one way I might read your quote is as being against those who ripped the country apart after communism. I would guess that many young people see that as the last tragedy and not communism.

FWIW Yugoslavia was open to tourism during the Cold War. My father drove from the UK to Dubrovnik with a friend in the 60s. I retraced part of that trip about 5 years ago. I'd have seen more had this site and book been available, but I stumbled on a few of the places on their map.

Not on their map is Zeljava [1] which was an airbase with extensive underground tunnels under a mountain on the Bosnia/Croatia border. At the time, a few parts of it were cleared out with bits of spares amongst the debris. There is a UXO hazard away from worn pathways. This is highlighted by the mine signs. I think there have been a few accident since the war in the 90s, but inside there was a bigger risk from falling concrete (look up for blast door). Recent photos [2] show it has been cleaned up a lot.
