When you try to explain in writing complicate international and national stories, words are never enough. Especially when you must explain the history of thousand of years. Thanks to the modern technologies, you can better organize your words in a visual and very suggestive way.
The maps are one of the most useful tool even though you can start more than one war if your map is not as accurate as it is expected by one or the other part involved in the conflict.
Visual graphics, and slides are also improtant for explaining in a couple of key words what it is an issue about. You can show the connections between historical periods, the reccurence of certain topics, the connection between different personalities and even different level of family closeness.
The literary souls will complain that in the era of Internet, everything is oversimplified and is lacking the proper wording. The simple soul of a journalist will suggest that, at least when it comes to foreign affairs, you rather use the right word instead of too many words. Otherwise, you need histories of histories to find the right solution to neverending conflicts.
