The world has certainly changed a lot in those 27 years. I think the financialization of world's economies, the prevalence of offshore assets/shell companies(The Panama Papers et al.) and a global real estate and art market boom that seem to all but requires "hot" money, have all conspired to make sanctions less effective. That being said I don't think the world has ever seen this level or targeted sanctions so I suppose it's a bit of an experiment. The experiment itself does seem to support your question though I think.
