Why would the WTO and World Bank stop working with Ghana? Who would invade Ghana and why?
Usually a state in such a position is not very democratic or otherwise nice, but neither Venezuela, nor Iran, nor North Korea, let alone Russia, got invaded (for Russia, it's the other way around). Iraq was invaded, but Saddam's regime was the first to attack a US ally (the second invasion was poorly reasoned though).
Caveat being, this was to destroy the scud missiles launched at Kuwait, and then the US left. Agree about the second one though...
