Russian PMCs are now acting as the personal guard of Venezuelan President Maduro. This article also states that Russia is investing billions of dollars to back the country. https://www.reuters.com/article/us-venezuela-politics-russia...
At the same time, allowing an inept criminal syndicate friendly with the Russians to starve millions of people some hundreds of miles off the shores of the US is hardly a good idea either.
I'm generally against intervention but hopefully the Maduro regime is taken down somehow. This is hardly a fringe position either, most of South America and Europe has adopted the same position.
If anything I feel the US should be more involved there and less involved in the Ukraine and Syria.
So, fine ... Russia may be doing something there now. I don't know. But let's not be amnesic and remember that this situation persists since decades.
But you said it was "first you heard of that" or similar?
This "situation" is becoming worse. Hopefully it resolves soon.
