This is going to be a drawn out mess which no one except Maduro wins, since it's in his interest to distract from the problems in Venezuela and to bolster his chances of reelection in Presidential elections in 2024. He doesn't have to do much, just rattle sabres every now and then to keep it in the news.
The biggest losers are likely to be the Venezuelans who fled to surrounding countries (including Guyana) due to the collapse of the Venezeulan economy, and who are likely to face a backlash of sorts.
