NYC–to–Dakar is an eight hour direct, the food is good, the infrastructure is decent, and Americans might learn that not all Muslims are Arabs. Of course, the fact that there would be honest concerns about setting up shop in a country as relatively stable and modern as Senegal underscores why it looks like the move will be Stateside.
There's no point having an AFRICOM if you are going to base it in the States (different time zones, distance etc.). Give it up. AFRICOM could have made sense thirty years ago, not today.

It just doesn't make sense.
