...per week. I highly doubt their goal is to inform you on all current events in the region in a single week. But it's a weekly and over time a reader would develop a cursory understanding of events across the region (they also briefly touch on the highlights in the "The World This Week").

I think they're assuming their readers will know how to dig further on events they find relevant. Personally I find The Economist pairs well with a subscription to Foreign Affairs.

Is there any news source which gives that level of detail?
