Ideally you are correct with some of the influence the Western countries have on the third world countries, they set up proxy leaders that govern the affairs of some of this countries, however I found it very unease that some of these things still happen in present day, this is because i believe people are more educated and wiser now, so if the leaders in your country is not doing the bidding of the ordinary citizens, I feel there is need to revolt against such government, a government is supposed to be set up to fulfill the basic needs and governance of the people, "the voice of the people is the voice of God" they say, so I feel there is need for the third world countries or underdeveloping countries to stand up and confront situations themselves.
When you revolted in Nigeria what happened? People were slaughtered by the military. The West is aware that many protesters were killed during the End SARS protests. The current president contributed to the massacre. His son was in charge of the electronic billboard that was lighting the area protesters' camp. The billboard was intentionally switched off to enable the military to kill protesters. Did the US or other Western countries declare the leaders wanted? No, because they are Western puppets. But they can justify the Kidnapping of the Venezuelan President and the blockade of Cuban ports because these Presidents are anti-West.
The International Court of Justice was created to prosecute only leaders who are hated by the West. If you want to be protected as a leader, become a puppet of Western powers.
