(CNSNews.com) – Nation of Islam leader Louis Farrakhan, continuing his controversial visit to Iran Thursday, warned President Trump that U.S. policies in the Middle East, at the behest of Israel, “will end America as you know it.”

It is not the Iranians’ chants of “Death to America” that will bring down America, he told reporters in Tehran, but U.S. policies that will produce that result.

“I am begging our president and the government that supports him to be very, very careful,” Farrakhan said. “Because if the trigger of war in the Middle East is pulled by you, using your surrogates at the insistence of Israel, then the war will trigger another kind of war which will bring China, Russia, all of the nations into a war.”

“And it bothers me to say this to you, Mr. President, but the war will end America as you know it.”

“When these Iranians chant, ‘Death to America, Death to Israel,’ no chant can bring about your death,” Farrakhan added. “But it is your policies that are eroding trust for you in the world, favor for you in the world.”

“And if you do this, you will bring about – not the Iranian chant – you will bring about the death of the greatest nation.”

Farrakhan has bristled at media reporting saying that during an earlier part of his visit he led students at Tehran University in chants of “Death to America.”

In a statement this week, he accused “U.S., British and Jewish publications” of falsely reporting that he had done so.

“I asked a question about how to pronounce the chant in Farsi during my meeting with Iranian students and an examination of the video shows just that,” he said in the statement, calling the reporting “a blatant falsehood.”

Iranian media outlets reported that Farrakhan led the chants, although CNSNews.com in its earlier reporting raised doubts about that portrayal of his actions.

On Thursday, Farrakhan got tetchy when he understood a reporter with Iran’s state-funded Press TV to be inviting him to chant “Death to America.”

“Who sent you to ask that question?” he said, adding that the reporter seemed to be “one of those who are paid at Press TV to provoke that.”

Farrakhan blamed U.S. sanctions against Iran – recently restored after Trump withdrew from the nuclear deal – for Iranians’ anti-U.S. slogans.

“I know that chant came from the people of Iran, and this sanction is hurting the people of Iran – they have the right to chant it,” he said. “But I am not a chanter, I am a worker for God, and the truth will undo falsehood and the righteous will win against the wicked.”

Farrakhan also took issue with those who criticize him for condemning U.S. policies.

“America is ours. Our sweat and our blood built America,” he said. “How dare you say that we have no place there? How dare you say that we cannot criticize your evil and point it out to you?”

“I am more of a patriot than most of you who bow down to evil, and it is only truth that will make America better,” he said. “And I speak that truth, and I will be back in America to speak it again.”

During his earlier visit to Tehran University, Farrakhan contrasted the policies of Iran and America – in a way that favored Iran.

“Is it not true that you have called America the Great Satan?” he asked the students. “Well, if you believe what you say, then would not Satan be actively involved in trying to destroy a nation that is set up on the belief and practice of submission to the will of God?”

The U.S. was making it difficult for Iran to “carry out its mission,” Farrakhan said. “But if you have the strength to persevere under these hard trials, the victory will be yours.”

Among controversial figures Farrakhan met with during his visit were an ayatollah who has questioned the Holocaust, and with a senior official wanted by Argentina in connection with the deadliest terrorist attack in that country’s history.
