Well, the good thing about being Belgium is that you're too weak to do much. We didn't do much to protect our Jews in WWII. Our police was incompetent enough to search the house of our national monster (Marc Dutroux) while two kids were alive in his cave/sex dungeon and not find them. We killed Patrice Lumbumba, the last half-decent Congolese leader. We introduced ID cards with the ethnicity on them in Rwanda, and didn't do much to try to stop the genocide.
Belgium host SWIFT institution, nato, European institutions, is a hub of the Freemasons and other orders, and one of the most important actor of European construction. Our politicians are everywhere and the remaining colonials have a huge impact on Africa.
What happened to Lumbumba was a bit more complicate than that, though, and he made a decision that cost Congo a lot with his last discourse.
We are extremely rich, with a lot of savings, and could have a huge impact on the word. Despressingly, most Belgians don't realise it and believe we live in a "small, harmfull country" when we live in possibly the most influencal country for its size.
