Hossein Dehghan, an adviser to Iran’s Supreme Leader Ayatollah Ali Khamenei, is warning that any American attack on the Islamic Republic could set off a “full-fledged war” in the Mideast in the waning days of the Trump administration, The Associated Press reported.

“We don’t welcome a crisis. We don’t welcome war. We are not after starting a war,” Dehghan said speaking to The Associated Press. “But we are not after negotiations for the sake of negotiations either.”

“A limited, tactical conflict can turn into a full-fledged war,” he said. “Definitely, the United States, the region and the world cannot stand such a comprehensive crisis.”

Dehghan, who is a possible 2021 presidential candidate in Iran, said any negotiations with the West could not include his country’s ballistic missiles, which he described as a “deterrent” to Tehran’s adversaries.

“The Islamic Republic of Iran will not negotiate its defensive power ... with anybody under any circumstances,” he said. “Missiles are a symbol of the massive potential that is in our experts, young people and industrial centers.”
