This is also where the US has/had the largest military drone base in the world.
Seems like a pretty big deal, specially with Burkina Faso seeming like it's going in a socialist direction again.
Also Burkina Faso’s Ibrahim Traore: “Today, our relationship with Russia is primarily strategic. With Russia, there are no restrictions on the equipment we want to purchase. Others impose restrictions on us. They support us in terms of training, logistics, tactical training, and everything else. They provide support in these aspects."
Why would anyone in a military conflict ally with the US anymore if all it takes is a couple corrupt dipshits in Congress to leave them all completely defenseless during their time of need.
It needs a 'base', at every part of the world, which would become a hub for any kind of future deployment. Anyway, it's not just the US, it can be any powerful countries. It just matter of how they do it, nice or not so nice way, direct or indirectly. China does it through business, e.g. silk road.
It's more because Russia's interests and economy are Global South-oriented already and against imperial core countries. This has become even more true since the current war started.
Though not as much as USSR-times when they used to fund Vietnam, Bangladesh, Korea, Palestine, Cuba, etc without the profit motive that is necessary under capitalism.
