This might seem a stupid comment, and it probably is, but looking at the most difficult languages list at the bottom (Arabic,Chinese,Japanese,Korean) the first thought that came to mind by looking at the pattern was "the US (largest English speaking country) have been at war with countries speaking two of these languages, might be at war soon with a country speaking another one and surely are not best friends with the country speaking the remaining one".
This could be pure correlation without any cause-effect, but I still wonder how easy would be for any country to go to war with another one when most citizens of both countries spend years communicating each other. The usual propaganda which depicts others as demons in order to fuel hatred and "sell" the war to the public would be a lot more difficult.
