I work with a bunch of Bosnians - both Bosnian Serbs and Bosnian Muslims - here in the U.S. They think that I'm crazy to want to go back to Antarctica, and I think they're crazy . . . for many reasons.
You might still have a chance to go. You didn't say which African country you are in, but South Africa has an Antarctic program. I'm sure they need IT engineers.
Besides that, there's a fair amount of international cooperation in the Antarctic. I've seen Japanese scientists, Swedish scientists and support staff, New Zealanders, Canadians, British, and even a Bulgarian at U.S. stations, and next year there will be at least one each from France and the Netherlands. Start asking around, and let us know what happens.
