Trump’s record of leaking intelligence and doubts over his new team have allies worried, experts say

With days to go until America decides who will become the next president, there are concerns among some US allies over one of the most important aspects of their relationship with the world’s most powerful nation — intelligence sharing.

While a Kamala Harris presidency is expected to fit into a more predictable pattern of intelligence handling, security experts say some US allies have more “anxiety” about the alternative: Donald Trump’s return to the White House.

The Independent spoke to experts in intelligence, national security, and foreign policy from the UK, Australia, and Canada on the implications of a second Trump term. They all agree that the stakes couldn’t be higher – and suggest that the Republican candidate’s track record when it comes to leaking secret information is one of their causes for concern.

“There is trepidation about Mr Trump in the US intelligence community and throughout the Five Eyes network,” Dr Michael Fullilove, executive director of Australia’s Lowy Institute for International Policy in Sydney, tells The Independent, referring to the intelligence-sharing network made up of the US, the UK, Australia, Canada, and New Zealand.

“The handling of secrets requires people to follow rules,” Fullilove says. “But Mr Trump doesn’t seem to believe that rules apply to him. He sees himself as existing in a rule-free zone. When you’re talking about the handling of classified intelligence, that’s a problem.”

During Trump’s first administration, the White House “leaked like a sieve,” Dr Daniel Larsen, a lecturer in intelligence and war studies at Scotland’s Glasgow University and previously at Cambridge, tells The Independent.

As a matter of law, a sitting president can declassify the most secret classified information, but US defense experts say even presidents have to transmit declassification orders through the proper channels.

Despite the leaks from Trump’s first term, experts largely agree that intelligence sharing between the allied nations would continue under a second Trump administration, but they acknowledge there would be some level of risk.

Professor Thomas Juneau, a former defense analyst with Canada’s Department of National Defense, explains that his country relies heavily upon the network as it “gets way more than it gives.”

“Is Trump going to kill the Five Eyes on day one? No. That’s way too extreme. But it is conceivable,” says Juneau, an associate professor at the University of Ottawa. “Is it conceivable that in four years, the Five Eyes are weakened and that we don’t necessarily get as much through as we used to? Yes, of course it is.”

Fullilove, of the Lowy Institute, maintains that the Five Eyes “will survive” Trump, and says the assertion that US allies would stop sharing information with the Americans if he were elected is “unrealistic”. But he adds an important caveat: “Trust is critical.”

Kim Darroch, a former British ambassador to the US who resigned in 2019 following the leak of some of his dispatches that were critical of Trump, told The Independent that the relationship between the UK and US intelligence communities “is close, strong and durable” and “will flourish whatever the political climate.”

Christopher Steele, the former head of MI6’s Russia desk who found himself at the center of a worldwide controversy after he authored the so-called Steele dossier, a series of startling allegations suggesting Trump might have been compromised by Moscow, has a much graver assessment. He tells The Independent that concern among British intelligence officials “should be very high” if Trump is re-elected.

“I don’t think we can feel confident that any information that we give America as part of our very close and very important intelligence and security alliance would be safe,” Steele says. “In my 40-year career, I’ve never felt so concerned about the state of the world.”

In 2019, a US Department of Justice report found that the FBI had “raised doubts about the reliability of some of Steele’s reports”. However, Steele maintains to this day that the dossier — an intelligence report collated for a private client — contained “original intelligence [and] was obtained from credible sources.”

In a new book titled Unredacted, Steele warns of “a new world disorder” if Trump takes back the White House next week.

The view on Trump’s home turf was that some of his behavior was “very disturbing” to those in the intelligence world, according to former New York Times correspondent Thom Shanker, who covered the Pentagon, the military and national security for the paper.

In June 2023, prosecutors unsealed an indictment that contained photographs of boxes of classified information stacked in Trump’s Mar-a-Lago bathroom.

“That’s kind of what really shocked people,” Shanker, George Washington University’s Project Director for Media and National Security, tells The Independent.

“They were just in the open, where countless numbers of people just walked by and could have reached in and grabbed some or read them. So I think that was very disturbing to a lot of people who work in that world.”

Joe Biden’s home was also raided by the FBI in early 2023 after it emerged that he, too, took classified documents home with him when he was vice-president. Biden complied with the investigation, and no criminal charges were brought. Trump, however, was accused of a cover-up.

“When confronted with it, one cooperated with investigators, one obstructed,” Shanker says. “Taking the classified documents home is less telling than how they responded once they were confronted with it.”

So what do US allies think Trump 2.0 might look like?

Darroch says he is more concerned about a potential second term.

“Back in 2016, Trump had never served in any level of government, so was entirely inexperienced on how to make things happen,” he tells The Independent. “And he brought some mainstream Republican figures into government who turned out not to share his ideas and objectives.”

He continues: “If he wins a second term, it’s clear that he will appoint only supporters to positions around him, and he will have learnt from his first four years how to deliver. So bad ideas are much less likely to get stopped.”

Juneau says it would be “naive” to assume Trump’s second term would be like the first.

“My fear is that Trump two will be different,” he warns. “And the assumption that many are making here in Canada, but elsewhere too — that we survived Trump one, so we’ll be OK with Trump two — I find that that’s a naive assumption, even if it’s not completely impossible. Trump two will hit the ground running.”

Allied security services will be keeping a watchful eye on anyone Trump potentially nominates to head up the CIA and the NSA if he wins a second term.

“The thing that British intelligence would be watching like a hawk would be who he appoints to those positions,” says Larsen, the British intelligence historian. “There would obviously be more anxiety about a Trump administration just because of the much greater uncertainty as to who he might appoint and what those appointees might do.”

British officials, Larsen adds, would consider whether Trump appointees “might do something that would fundamentally change the bureaucratic relationship between these agencies on both sides of the Atlantic. [Whereas] with the Harris administration, you could count on the pretty traditional appointees to these organizations who would leave the relationship in place as it is,” he says.

Differences in foreign policy could include Trump’s attitude to Nato, the 32-member Western defense organization, which he has repeatedly criticized. In February, he said the US would not help defend members who failed to spend 2 per cent of their GDP on defense, as per NATO targets. Instead, he said, he would tell the Russians to “do whatever the hell they want”.

John Bolton, who served as Trump’s national security adviser, has said he feared Trump was planning to pull the US out of NATO completely. Some observers suggest he may do that in a second term, or perhaps just make clear that he would not back NATO’s Article 5 commitment to come to the defense of any member that is attacked.

Trump has also repeatedly praised Russian president Vladimir Putin, among other dictators. At a joint news conference in Helsinki in July 2018, Trump surprised onlookers by taking Putin’s word over that of US intelligence agencies on the issue of whether Russia had interfered in the 2016 US election.

Unlike the first administration, Juneau says, Trump would “surround himself with people who will loyally implement his true vision from day one.”

“Jim Mattis, the first secretary of defense, some of [Trump’s] first national security advisers, some of the people at the CIA, like [Mike] Pompeo, they were Republicans. They were conservatives, but they were professionals, and they were actively blocking Trump’s craziest ideas,” says Juneau.

“The fear has got to be, from a Canadian national security perspective, [that] that won’t be the case under Trump two.”

Fullilove agrees that Trump “leant on the so-called adults in the room” when he was first in office. “This time, he has said that he doesn’t want those kinds of people in the room, and many of them will choose not to be in the room with him because they’ve seen what happened to the people who served him in his first term,” he adds. “So you are likely to see more Maga characters in senior positions.”

But Fullilove stresses that while “it would be harder” a second time round, Trump would not go completely unchecked. “On the other hand, don’t underestimate the resilience of the American system: the permanent civil service, the military, the Congress, the courts.”

He is also encouraged to hear JD Vance express his support for AUKUS, the trilateral security and defense partnership between Australia, the UK, and the US — but warns that there is still “some nervousness” because of his running mate.

“I asked JD Vance about AUKUS at the Munich Security Conference in February, and he said that he’s a fan,” Fullilove said. “The problem is that Mr Trump has no personal stake in AUKUS, and he has made a habit of ripping up deals that his predecessors signed. So, there is some risk to AUKUS. I wouldn’t overstate it, but there is some nervousness in Canberra.”

When approached for comment, the Trump campaign claimed that the Harris-Biden administration has “put our national security at risk more than any administration in history.”

Karoline Leavitt, the Trump campaign’s national press secretary, said in a statement to The Independent: “When President Trump was in office, NATO was strong, there was no war in Ukraine, and the Middle East was stable. Under Kamala Harris, the entire world is on the brink of a major war as Putin continues his crusade into Ukraine and Iran is funding terrorist attacks against our ally, Israel.”

Leavitt added: “President Trump will restore world peace through American strength and ensure European nations carry their weight by paying their fair share to our mutual defense to lighten the unfair burden on American taxpayers.”

As Americans head to the polls on Nov. 5, the world holds its collective breath as the count to determine the most powerful politician in the world goes down to the wire.

“The world is in the most fragile and dangerous state that it has been for a generation with war in Europe, conflict in the Middle East, and tension with China,” Darroch said. “Against this backdrop, the American people’s decision on who leads them for the next four years is more consequential than ever.”
