I think the whole long-haul holiday business is going to suffer even more than it is already. Anecdotal I know, but a friend recently pulled out of buying a beautiful holiday property in Thailand. It was partly an investment and he doesn't think it's a good one anymore and that was even before the latest plot.
I don't know the answer. It's worrying that we have reached this stage without any big trigger like 9/11 was. I can't believe that a passenger jet hasn't been shot down yet by a surface-to-air missile - surely that's only a matter of time and what will happen then?
