Honestly its rude to be invited by a country to meet their president who decided to respond to your criticisms of their administration only to not show up and go meet the opposition.
Being invided and then no showing shows complete disregard to basic diplomatic Etiquette since it was a mission to show solidarity against the embargo
Bonus socdems being cringe part 4.5: about another member that didnt show up to the presidential meeting
Show
Deeply unserious people
Maybe she should have then attended the meeting with the President of Cuba who offered to address her criticism then instead of declining the meeting and running off to speak to the opposition while giving credence to Miami gusanos
