What is the name of the game in post #2, pics 2 and 3? It looks like some kind of cold-war-risk, judging from the board.
Has anyone ever tried 'Junta'?

Definitely not a game for every week, as we sometimes still argue after years about betrayal and backstabbings - and if you play good you cannot avoid to play like this. The most important rule, even written in the manual: "Always remember: it's only a game!"
