The reason why Maduro is in power is the US. Plain and simple.
Hadn't the US propped puppet right wing governments in Venezuela, there wouldn't have been a need for a Chavez mesias.
The US doesn't care about drugs. They care about Venezuelan oil and continue tal hegemony. That's it.
So, it's not only Trump. It's every single government before him.
Hahaha, we can always hope.
