I'm also worried about this but want to bring in these thoughts from the news mega:
Really doubt Maduro will actually invade Guyana. Venezuela is only doing this now because the US wanted to build military bases around the Venezuelan border since they can't use Brazil or Colombia territory anymore as their base for a land invasion of Venezuela.
i’m not so sure. while Maduro certainly doesn’t seem like a mad, blinded nationalist intent on expanding borders, there’s more to the crafting of state policy than just the executive’s vibe.
if he has enough realistically and proactively thinking military and foreign policy men around him, they could convince him that it’s vital to readjust their borders where they can while the US is distracted, instead of skipping out on the opportunity and keeping up appearances on the world stage. once the US’ hold over Europe wanes, it could very well start focusing on consolidating its power in the Americas again, and any leg up you can get on the colossus while it’s not looking your way could be the difference between survival or getting the Operation: Iraqi Freedom treatment.
