Think you better check your timeline there - the communist regime in Romania fell, and Ceausescu was executed, in 1989. Pacepa defected in 1978, and if he "saw the writing on the wall" eleven years in advance, then he was a hell of a lot more prescient than, say, the CIA.
True, he didn't leave at the last minute, but everyone knew those regimes were heading down hill, especially the men in charge of keeping all the secrets. Maybe some of the dictators were to far gone to know better, like Saddam thinking he could defeat the US military vs his generals who knew better, but the intelligence guys knew what was to come. Now this mass murderer and builder of one of the worst regimes in European history is an "acredited" voice who gains respect and speakers fees without once ever having to face his victims. Ask him if he's been back to Romania since. My bet is no and never will.
