CIA chief warned Moscow as Russia threatens UK over missiles
Central Intelligence Agency Director John Ratcliffe made a rare Moscow trip this week to warn Russia against attacking NATO allies, especially Estonia, Latvia and Lithuania, after US intelligence flagged a possible limited assault. Moscow simultaneously threatened UK military targets over Ukraine's use of British long-range missiles.
The unannounced visit followed reports in the Wall Street Journal and Politico that Ratcliffe delivered the NATO warning in person. He arrived on a US Air Force C-17 transport with an American motorcade, signalling Washington treated the intelligence as urgent, according to the Institute for the Study of War.
Key Takeaways
- CIA Director John Ratcliffe warned Russian officials in Moscow not to escalate against NATO, particularly the Baltic states.
- US assessments suggest Russia could test NATO with limited strikes, drone incursions or small land operations rather than a full invasion.
- Russia threatened UK military installations inside and outside Ukraine over British missile support for Kyiv.
- The Telegraph reports Putin could deploy unmarked "little green men" tactics used during the 2014 Crimea annexation.
- Baltic leaders say their immediate threat assessments are unchanged but stress NATO unity as the best deterrent.
Why Did the Central Intelligence Agency Chief Visit Moscow?
Ratcliffe's visit is only the second known trip by a CIA director to Moscow in recent years. William Burns made the last such journey in November 2021, attempting to deter Russia's full-scale invasion of Ukraine.
ISW assesses the 2026 context is different. There is no evidence of a large Russian military buildup on Baltic borders comparable to 2021. However, Washington appears concerned Russia may prepare a limited act of aggression to test and potentially break NATO's Article 5 mutual defence clause.
Russian Foreign Intelligence Service director Sergey Naryshkin confirmed on August 27 that he met Ratcliffe. Kremlin spokesperson Dmitry Peskov dismissed media reports about NATO aggression as having "nothing to do with reality."
Could Russia Use 'Little Green Men' Against NATO?
Reporting in The Telegraph warns Vladimir Putin could revive tactics from the 2014 Crimea annexation, when unmarked soldiers in green uniforms — later acknowledged as Russian troops — allowed Moscow to deny involvement while seizing territory.
Analysts cited by the paper consider a straightforward military assault on the Baltic states unlikely. A limited incursion, cyberattack or hybrid operation in Estonia or elsewhere could instead probe whether NATO would respond unanimously under Article 5.
ISW notes Russia could conduct air, missile or drone strikes or a small land incursion without the visible buildup that preceded the 2022 Ukraine invasion. The Suwalki Gap, linking Poland and Lithuania between Kaliningrad and Belarus, remains a longstanding strategic concern for NATO planners.
What Did Russia Say About UK Military Support?
Amid the CIA visit, tensions between London and Moscow escalated sharply. Foreign ministry spokesperson Maria Zakharova warned Russia could strike British military targets inside and outside Ukraine in response to Ukrainian attacks on Russian territory using British long-range cruise missiles.
Zakharova said London was "one step away" from what Moscow considers legal complicity in "terrorism" against Russian civilians. She urged British leaders to analyse the situation carefully to avoid "inevitable catastrophic consequences."
The exchange coincided with UK announcements of further military support for Ukraine, including access to classified Storm Shadow missile technology, according to Sky News reporting on the widening conflict.
How Are NATO's Baltic Allies Responding?
Despite Ratcliffe's urgent delivery, Baltic officials sought to reassure their populations. Estonian Foreign Minister Margus Tsahkna said on August 27 that Estonia's threat assessment had not changed, while stressing that provocations against NATO must be taken seriously.
Latvian officials similarly downplayed the risk of an imminent conventional invasion. Think-tank analyst Kristi Raik told Estonian media there is "no ground" to compare today's Baltic situation with Ukraine in late 2021, when clear invasion intelligence existed.
ISW concurs that a near-term full-scale Russian invasion of the Baltics is highly unlikely. The more pressing concern is a limited operation designed to fracture NATO unity — a scenario high-level intelligence and security analysis now places at the centre of allied planning.
