NATO is a purely defensive alliance, not a battering ram.
You can definitely see how this isn’t true, right? It’d be incredibly problematic to be opposed by NATO and to have NATO creep up to your borders. Superpowers flipped their shit over stuff like this in the cold war all the time. It’s not any different today.
If you’re part of the global south, there’s a decent chance NATO opposes you or someone you’re closely affiliated with. Is your suggestion to those countries for them to just not be part of the global south?
Because that’s incredibly hard to do.
