The difficulty is finding brief introductions to the overall situation. Thankyou
@The Revolting Man, PragerU does have a good video outlining the standard viewpoint on it for use as an introduction to the history for children who weren't born at the time. But other than that, most material jumps straight into details and assumes you already know the overall historical events. This is true for both mainstream sources (e.g. everything on the "Falling Man") and even more the case for everyone offering alternative perspectives on events. Most people want to teach you more about a detail that they have studied at length, and make multiple-hour-long documentaries digging into that detail, full of imagery that is unsuitable for young children. Or are very focussed on shock-horror imagery aimed at inducing an emotional reaction. Few step back to present a simple historical narrative succinctly. That's the sort of thing we're really looking for. Maybe most people are still too closely connected to the events to look at them as a dispassionate historian?
Several 5-30 minute videos and/or articles that take that sort of reading time for a young person, presenting the whole thing from different perspectives that the child can then compare and contrast, would be good. PragerU gives an excellent starting point.
