One week after President Donald Trump’s administration recognized an opposition leader as Venezuela’s interim president, the Latin American nation’s disputed leader Nicolas Maduro warned Wednesday that the United States was in danger of turning his country into another Vietnam War.

“People from #USA, I ask for your support in order to reject the interference of Donald Trump’s administration which intends to turn my Homeland into a ‘Vietnam war’ in Latin America. Don’t allow it!” Maduro posted on his Twitter account, in English.

In a video published in Spanish on his Facebook account, Maduro said if “the U.S. intends to invade us, they will have a Vietnam worse than they can imagine.”

Maduro has accused the U.S. of attempting to stage a coup against his government. Speculation that Trump may be preparing to send troops to Venezuela was fueled this week after National Security Adviser John Bolton was seen holding a notepad that read: “5,000 troops to Colombia.” Colombia borders Venezuela.
