Alexander Dugin, the fascist philosopher known as “Putin’s Rasputin”, said: “The capture of Maduro demonstrates that international law no longer exists — only the law of force applies.”

Alexey Pushkov, a Russian senator, accused the US of returning the world to “the savage imperialism of the 19th century”, adding: “Won’t the ‘triumph’ turn into a disaster?”

“The United States carried out a coup in Venezuela, struck the country, and demonstrated that international law means nothing to a nation that considers itself a hegemon,” said Igor Girkin, a former soldier and FSB officer turned commentator.

According to Michael Kofman, a Russian military analyst at the Carnegie Endowment for International Peace, the Trump administration’s decision to strike Venezuela without even the “veneer of justification” “substantially frays” any sense of international order.

He adds that it “will make it much harder in the future for the US to convince other states that this type of behaviour should be punished”.

“By using force to assert its hegemony in the Western Hemisphere, the US is trading these short-term gains for a long-term structural cost to its overall position in the international system and to the advantages it enjoys over its rivals Russia and China,” he said.

“We live in a world, in the real world, Jake, that is governed by strength, that is governed by force, that is governed by power,” he said. “These are the iron laws of the world since the beginning of time.”

The statements by the two men amount to an explicit declaration of gunboat diplomacy and an embrace of the kind of 19th-century U.S. imperialist policy in the Western Hemisphere that has been widely criticized across Latin America.

Senator Mark Warner of Virginia, the top Democrat on the Senate Intelligence Committee, said in an interview that decades-long efforts by the United States to prove it is not a colonial power in the Americas has been “all thrown out” now, and that Mr. Trump’s actions could “potentially turn the whole region against us.”

He added that the administration’s aim of dominating the Western Hemisphere — including forcibly seizing leaders in the region — could spur China and Russia to try to do the same in their perceived “spheres of influence.”
