I've been pondering it for hours... 98% it's a threat about kidnapping Americans, put the word "ransom" in place of "bonus". A non native English speaker could easily confuse the two words. It's like when you are in a hurry and the precise word in another language escapes you for a moment, but you toss in a placeholder, knowing that the person you're talking with will fill in the right word from conversational context. This is a shitty vetsion of "Look at me. I am the Captain now."
There are a few people in the Army who are world-class champions at "you leave you move you vanish". They went to a lot of trouble to import their Xboxes to Niger. Do not enter random shitty quarters and touch xboxes.
Credibility alert: based on this article, the situation in Africa looks quite horrible from a US/NATO perspective. I know China and Russia are trying to expand there, but do we think they are just filling the vacuum, or were they the one to initiate some military coups?
