Seven years ago Venezuela was becoming an economic giant.
Then they confiscated the guns and went socialist.
Three years later Venezuelans are eating their pets to survive. Seven years later the government is shooting Venezuelans to prevent them from obtaining humanitarian aid.
Maduro did not prevent humanitarian aid EXCEPT for aid from the US. The EU, Red Cross International, and the allies you listed earlier are all supplying assistance. Maduro made it clear he would not accept humanitarian aid from the US and we ignored him and piled up our sacks of rice on the border tut-tut-ing about what a horrible guy he is, making it look as if he was doing nothing to help his people.
Our government can be pretty slimy when it wants, you know?
