Discrimination on grounds of national origin should not be tolerated. The only real victim of official Tunisian anti-Semitism... was Tunisia’s own tourism prospects.
I applaud the company for cancellation of future port calls in Tunisia. Its heartening to see a company stand up for its customers these days. Norwegian Cruise Lines absolutely 100% did the right thing here.
It might have been "official Tunisian anti-Semitism", or it might just have been the Tunisian government not wanting to risk having Israelis murdered there by local jihadis (which would REALLY have shut down tourism).
