Why did Trump order the invasion and extradition of Maduro out of Venezuela to install a regime other than the rightfully elected leader? Because she is female and won the Nobel Peace Prize instead of him.
And yes, he is so petty and jealous to start this campaign just to have bragging rights that he is running Venezuela instead of her. Think about, this makes much more sense than liberation or even access to their oil reserves. Those are only after the fact excuses to justify his behavior.
