π A Havana syndrome device?
Plus: Movie of the day

Todayβs briefing: |
|
Good morning Intriguer. Iβm often guilty of telling folks that I think the world peaked in the early to mid-2010s. Back then, social media was mainly filters and viral challenges, and PSYβs Gangnam Style was top of the charts. Yes, there were still geopolitical conflicts, but the world felt like it was trending in a positive direction.
Such is the beauty of nostalgia bias, under which one highlights the pastβs positive memories while diminishing its negative ones. One of the nastier memories that I tend to gloss over from the 2010s (aside from skinny jeans) is βHavana Syndromeβ, a mysterious ailment that was the talk of the diplomatic community during my time in the foreign service.
Ten years on, thereβs been some interesting developments. Thatβs our top story for today.

P.S. Todayβs newsletter will be our last one for this week. Weβll be taking a quick break for our team retreat this Thursday and Friday, and be back in your inboxes next Monday.
Intrigue Insight: Iran update
A quick update on the situation in Iran:
-
US President Donald Trump took to social media to tell Iranians to βKEEP PROTESTING – TAKE OVER YOUR INSTITUTIONS!!!β, adding βHELP IS ON ITS WAYβ without clarifying further details on what the βhelpβ would entail.Β Β
-
US officials reportedly met with Reza Pahlavi, the son of the ousted former Shah, over the weekend. Pahlavi is angling to position himself as a potential transitional leader in case of the regimeβs collapse.Β Β
-
Meanwhile, protests continue in Iran despite a violent crackdown. Thereβs no way to verify the number of casualties, but by most accounts itβs now squarely in the thousands, if not tens of thousands.Β
-
Elon Musk has reportedly made Starlinkβs satellite service free for Iranians in an effort to combat the multi-day communication blackout imposed by the authorities.Β
-
Meanwhile, regional players watch on. The UAEβs Minister of Foreign Trade, Thani Al Zeyoudi, said that the USβs threat of 25% secondary tariffs for countries that trade with Iran has βyet to be sorted.β
Quick Take:Β As we wrote on Monday, the regimeβs collapse is not a foregone conclusion. But the longer these protests continue, the more precarious the regimeβs position becomes, which could drive an even bloodier crackdown.
Mystery device

Picture it: a secluded hangar, a furtive handoff, goons with guns, suitcases bursting with cash. On one side, US operatives. On the other, sellers with a mysterious device that might finally explain Havana Syndrome.
You'll forgive our imaginations running a little wild there, but according to new reports from CNN, the source material is very much real: in the dying days of the Biden administration, a branch of the US Department of Homeland Security, clandestinely purchased a device that could be the cause of Havana Syndrome.
But first, some contextβ¦
For those who remember the 2010s, you may recall stories about Havana Syndrome βofficially called Anomalous Health Incidents (AHIs) β a collection of neurological and other symptoms that hit US diplomats, spies, and their families around the world.
Those affected reportedly experienced a range of ailments, including dizziness, nausea, headaches, ringing in the ears, and dull pain.
The condition earned its nickname because the symptoms initially presented in US and Canadian officials who had worked in Cuba around 2016. Since then, hundreds of similar incidents have been recorded by US personnel posted at several locations, including Guangzhou, Vienna, Hanoi, BogotΓ‘, and Tbilisi.
But hereβs the puzzling bit: a decade on and we still donβt know what causes it. Years of studies have produced three competing theories:
-
Environmental factors β perhaps exposure to toxic chemicals or other hazards. But this isn't supported by medical data, and the symptoms have appeared in locations with nothing in common.
-
A directed-energy weapon β most likely Russian. A 2020 study found symptoms "consistent with directed, pulsed radio frequency energy." And a 2024 investigation by The Insider, 60 Minutes, and Der Spiegel linked a Russian military intelligence unit to suspected attacks.
-
Psychogenic factors β stress, anxiety, or other natural causes. A 2025 National Intelligence Council report leaned this way, concluding it's "very unlikely" a foreign adversary is responsible, or even has a weapon capable of causing the symptoms.
The CIA sits somewhere in the middle of these assessments: an unreleased 2022 assessment dismissed the idea of a large conspiracy, but couldn't rule out foreign involvement in around two dozen cases.
Now back to this intriguing deviceβ¦
According to CNNβs unnamed sources, acquiring the device cost the US βeight figures.β It is reportedly small enough to fit into a backpack, has Russian components, and produces pulsed radio waves.
Those suffering from Havana Syndrome are hoping they might finally learn what happened to them, but the US has now had the device for a year and is seemingly no closer to solving the mystery.
Intrigueβs Take
Havana Syndrome has become a bit of an obsession in the US intelligence community.
For those affected, there's been a push for official recognition. Then-President Biden passed legislation to compensate those suffering from Havana Syndrome, but many remain unsatisfied by how the situation has been handled β including being publicly told the condition might just be in their heads.
Beyond the human toll, any direct evidence of a foreign power purposefully harming US officials abroad would be a serious diplomatic incident, at best, and a reason for a military response at worst.
But perhaps most importantly, isn't the US supposed to be the one inventing futuristic weapons and innovative methods of hurting its adversaries? Of course, trying to prove a negative is nearly impossible, but the fact that, nearly a decade later the mystery remains unsolved is an unnerving shortcoming of technological and intelligence capabilities.
Sound even smarter:
-
An important caveat: we only know what's been made public. There'd be significant intelligence value in the US not revealing what it actually knows.
Meanwhile, elsewhereβ¦

π¨π³Β CHINA β Donβt buy those chips. Comment:Β The Trump administration officially approved the sale of H200 chips to China just this week, but it seems like Beijing isnβt keen to have its companies rush to place orders. It could be a strategy to build leverage ahead of trade talks with the US, a move to force players into buying domestic semiconductors, or both. |

π°π·Β SOUTH KOREA β A death sentence for the former president. Comment:Β A three-judge panel is expected to hand down its verdict on 19 February. Despite the prosecutorβs request for a death sentence, the court is more likely to impose life imprisonment: South Korea hasnβt carried out an execution in three decades, and Yoonβs death at the hands of the state risks further political polarisation. |

π»π³ VIETNAM β Made in Hanoi. Comment:Β This was only a matter of time, as Google now follows other big tech manufacturers (including Apple) in moving their manufacturing capabilities to Vietnam in an effort to reduce their reliance on Chinese manufacturers. |

Movie recommendation of the day

βThe Squareβ: When a real-life Swedish diplomat returned from his posting in Pyongyang, North Korea, the press were expecting tales of intrigue from inside the reclusive Hermit Kingdom. Instead, he told them his time there was simply βso lonelyβ and his only way to relieve stress was biking around on empty highways. Grim.
But his story inspired South Korean director Kim Bo-sol to dream up an animated film, The Square (pictured above), which has all the ingredients of a hit, including forbidden love with a North Korean traffic officer, diplomatic intrigue, and heart-wrenching decisions.

Yes, central bank independence matters (78%)
Β β No, it's just another headline (21%)
βοΈ Other (write in!) (1%)
Your two cents:
-
βΒ W.L: βFrame it any way you want but the competing priorities of each party are what comes out in the end.β
-
β Β S: βIt's really kind of strange that they'd even go down this path given that he's out in 5 months anyways.β
-
βοΈ R.B: βMajor reform of the FED is needed but like many Trump ideas, he correctly identifies a problem then makes it worse with his solutions.β
