He's a complete hypocrite and totally transparent. He got rid of Maduro from Venezuela, and the natural consequence should be that he installs the official opposition who are widely acknowledged to have won the recent elections but who were supressed and cheated by Maduro.
But no, Trump is not interested in democracy, only getting his greedy mitts on the oil so he leaves the existing regime in place with a more compliant leader. And he comes up with some pathetic excuse to deny Maria Corina Machado (who beat him to the Nobel Peace Prize) her rightful place back in Venezuela. And in his sad, deranged mind, he thinks people can't see through him.
