Please share the examples of the US “unilaterally invading” countries in Africa. I’m not aware of an example, but I’d love to learn something new.
If you are using fuzzy rhetoric to refer to various forms of political interference (clandestine or otherwise, legal or otherwise)... I would agree. But then the comparison vs. China and other world powers gets a lot muddier. Even the comparison between world powers and local powers gets muddy in that case. Politics, local or global, is historically ugly business.
The key global questions should be what frameworks of behavior do we want to condone? What justifications do we allow as legitimate nation-state motivations? How is it acceptable for states to treat their own people? (The last is particularly relevant when a state contains approximately 1/5th of humanity itself.)
Does China really offer a better vision to you?
