Former Secretary of State Mike Pompeo said Monday that Chinese President Xi Jinping is watching for "American weakness," after a four-star Air Force general surmised the U.S. will be at war with the world's most populous country by 2025.

Pompeo joined "Special Report" to discuss foreign affairs and the release of his new book "Never Give an Inch" when he was asked about the remarks from Gen. Mike Minihan.

"I take General Minihan to be serious, in the sense of he's clearly very concerned that we're not doing enough to prepare to deter the Chinese Communist Party," Pompeo said. 

"I think that's what he was really getting at – It's hard to put timelines on any of these things: he says 2025."

"But make no mistake about it, Xi Jinping is watching for American weakness. He's watching for an absence of resolve. And if he sees opportunity, he will seize that very opportunity."

Minihan is in charge of the Air Mobility Command at Scott Air Force Base near O'Fallon, Illinois, which oversees refueling and transportation-related aircraft. He reportedly wrote a memo that suggested war with China within two years.

"My gut tells me we will fight in 2025," Minihan wrote, adding that his officers should instruct service members with "the full understanding that unrepentant lethality matters most."

The Pentagon later tried to downplay the memo, according to the New York Post, with a spokesperson saying Minihan's comments "are not representative of the Department [of Defense]'s view on China."

On "Special Report," Pompeo also discussed the threat from Iran, which he said has been emphasized again as of late after three Iran-linked individuals were arrested and charged in the attempted assassination of an American journalist on U.S. soil.

"We know that the regime, the ayatollah and now [President Ebrahim] Raisi, the Butcher of Tehran, we know that these are folks who want to wipe Israel off the face of the earth, they're happy to come after America next," Pompeo said.

"We know that they're trying to strike Americans here at home. We saw that there were three folks indicted, arrested here in the United States, for trying to kill an American civilian."

"These are bad actors and our mission-set in the Trump administration was to deny them wealth and resources to reduce both their capacity to commit terror and to do the hard work, the work of the research and development of their weapons program."

Rafat Amirov of Iran and Khalid Mehdiyev – reportedly an Azerbaijani national living in Yonkers, New York – and Polad Omarov, of the Czech Republic, were charged with murder-for-hire and money laundering charges, according to an indictment from the Department of Justice.

The DOJ did not identify the victim by name, but only that they are a journalist and human rights activist based in Brooklyn, New York, with a history of highlighting Iranian human rights abuses and suppression of free expression.

Journalist Masih Alinejad later identified herself as the victim, saying "the country where I was born, Iran – the government wants to kill me, but my adopted country wants to protect me."
