He said they were particularly menacing given President Nicolas Maduro's renewed call this week for closer ties and request for a meeting with Trump at the U.N. General Assembly next month.
CIA Director Mike Pompeo said Trump, by raising the prospect of possible military action, was trying "to give the Venezuelan people hope and opportunity to create a situation where democracy can be restored".
"We are all over the world and we have troops all over the world in places that are very, very far away", Trump said.
"We have many options for Venezuela and by the way, I'm not going to rule out a military option", Trump volunteered, adding, "A military operation and military option is certainly something that we could pursue".
"The president is obviously growing impatient with a risky thug holding 30 million people hostage, with cowardly snipers murdering hungry democracy protesters", Roger Noriega, a former USA ambassador to the Organization of American States and assistant secretary of state for Western hemisphere affairs told McClatchy.
The president of Venezuela's new Constituent Assembly - the controversial body elected to rewrite the Venezuelan Constitution amid the country's political crisis - fired off a series of tweets late Friday slamming Trump's remarks as "cowardly, insolent and vile threats".
"In North American diplomacy, they never rule out the use of force, the military option". The vice president is expected to meet with each of the country's leaders, deliver a major speech on U.S.
Argentinean global law expert Paola de Simons told Xinhua that Trump was sending out "a warning, (as a) foreign threat, which belongs to what were decades ago".
A firm and clear response, which means that it won't see more than a few seconds of coverage in the press. "I don't think any decent person would blame him for considering options for putting an end to the people's suffering by putting an end to Maduro". Trump has shut the door on the idea until Maduro returns some sanity to his quickly deteriorating nation.
Military engagement in the turmoil in the South American country would mark a vast escalation in USA participation, which has thus far been limited to rebukes from the White House and economic sanctions.
After stifling all democratic opposition in his nation and essentially turning Venezuela into a communist dictatorship, President Nicolas Maduro responded to some tough talk from President Donald Trump by offering to set up a phone call and discuss matters.
Venezuela's government has been severely criticised by the global community for creating a National Constituent Assembly (ANC), which will rewrite the Constitution.
