Concorde's major issue when BAC was trying to sell it, was that countries didn't want the sonic boom happening over their country. Central Europe banned it, India banned it, Egypt banned it over cities etc. I think it was Singapore, Japan and South Korea where SST flights were not fully banned (though going supersonic over land would be banned).
It's worth looking at the sales pitch BAC tried around the world. BAC focussed on selling the aircraft to the Anglosphere and counties in the UK's and US' sphere of influence, while Aérospatiale focussed on selling the Concorde to Francophone countries.
Singapore Airlines cancelled their orders for Concorde when the price became known, Lufthansa cancelled their orders once Germany and France banned sonic booms over land. Quantas canceled after realising that the range of Concorde caused it to fly more at subsonic speeds than supersonic. Pan Am, TWA, Eastern, Continental, United Airlines and American Airlines cancelled their orders after SST flights were banned over the US (and after John F. Kennedy called all airlines to cancel their orders). JAL cancelled their orders after BAC flew Prototype 002 to Tokyo Narita and realised what a loud aircraft it was, and how much smoke the engines produced. Air Canada cancelled after both the US ban of SST Flights and the realistion of the limited routes Concorde offered (Gander and Vancouver were the only logical airports to base a Concorde).
In brief, Concorde was a sales mess, and the fact that only the governments of the United Kingdom and France bought Concordes for their own flag carriers showed how poorly thought out SST aircraft were. As great as Concorde was, no one wanted to fly it, or have it fly over their country. Countries close to the Atlantic or the Pacific could have made great use of Concorde tho
