Venezuela showed everyone what happens when you're a toothless country. USA shows up at your door uninvited, fucks your shit up, takes your oil and kidnaps your president for good measure, just to tack on some extra humiliation.
Don't get me wrong, Maduro deserved an even worse fate than what he got. Couldn't have happened to a nicer guy. It's still a cautionary tale for nations worldwide. It can happen to you. China continues to erode the economic power of the USA. They could very well discover one day that their military might is all they have left. Who's to say they won't suddenly decide to capitalize on their advantage before it evaporates?
