When you have "NATO" that does what it does, it wasn't really a shocker that eventually other nations would start to gather around. Mainly, India, China and Russia is the big three, Brazil is the fourth and not bad neither, they had some political instability in recent years as we all know, but not a small economy neither.
Places like Vietnam or Uganda is not what they are looking for ,they just want numbers, you think those actually contribute anything at all? They are just telling these nations "we can take care of you, you do not need USA anymore" and that's it, many nations cheerfully agree to that of course. Basically, competition is healthy and we needed this for a long time, let's see if it would have impact on economy in any good way.
