This is my point. You have linked many Wikipedia articles and if you follow up the references, they are nearly all media articles. Now there is nothing wrong with doing that to get one point of view but they are not reliable and tell the story from a certain point of view. To complete the picture one should examine all points of view while understanding that these may themselves be biased.
I do have some sympathy because getting to the truth on such a political topic may well prove impossible without significant time and possibly expense, but that does not mean that you should not at least try if the subject interests you.
