'This Would Be a Nuclear Genocide': Global Outrage Grows Over Trump's UNGA Threat Against Iran

President Donald Trump is facing global condemnation for his threat to "annihilate" Iran during a Tuesday speech at the United Nations General Assembly.

Dr. Tara Drozdenko, director of the Global Security Program at the Union of Concerned Scientists (UCS), said on Tuesday that the president's speech "clearly constitutes an implied threat to use overwhelming nuclear force against Iran and the Iranian people broadly."

"This would be a nuclear genocide," Drozdenko emphasized. "Any threat to use nuclear weapons is unacceptable, and his decision to do so should be strongly condemned by government, military, and civil society leaders."

Drozdenko acknowledged that Trump's long history of unhinged rhetoric might make his statements easy to dismiss, but warned even empty threats involving nuclear weapons can have serious real-world ramifications.

"President Trump’s nuclear threats against Iran reinforce a counterproductive lesson also imparted by President Vladimir Putin’s nuclear threats against Ukraine," she said. "Specifically, these threats encourage other countries to conclude that protecting and securing themselves from authoritarians with nuclear weapons requires obtaining their own nuclear arsenal."

Sen. Ed Markey (D-Mass.) also said that Trump's menacing rhetoric toward Iran must be taken seriously.

"Trump threatened to 'annihilate' Iran," Markey wrote in a social media post. "His 'October surprise' must not be a mushroom cloud from a nuclear attack. With these threats and assistance to Saudi Arabia, Trump is inferring mass slaughter and escalating an arms race in the Middle East. We must stop this madman."

Robert Tait, US correspondent for The Guardian, wrote an analysis on Tuesday arguing that Trump's threat against Iran was "stunning, even for him."

Tait noted that it has been decades since the UN General Assembly has "witnessed such a display of bellicosity from a superpower leader," especially since it was delivered in a "forum created in the aftermath of the Second World War, with the explicit aim of preventing future conflicts."

"Whether or not the latest threat should be taken literally," Tait added, "little of what he said about Iran seemed reassuring."
