I have written about Dubai's engrained apartheid and anti-semitism many times before (see here, here, and here for example). Today's Jerusalem Post reports that over a dozen Israeli cardiologists who had been invited to a Dubai conference of the World Heart Federation were denied a visa by authorities at the last minute.
If this had happened to any other national group it would have made world headlines and and led to international condemnation. But you can be absolutely sure that not a word about this incident will be said outside of Israel. And Dubai will remain a top holiday destination (even for an increasing number of British Jews) who believe the media propaganda that Dubai is an enlighted Arab Muslim country which welcomes all visitors equally.
