Denmark's defense intelligence has issued a stark warning regarding an anticipated escalation in Russian hybrid warfare against NATO allies, predicting a surge in cyberattacks and sabotage operations that could result in significant casualties. The report highlights a growing risk of attacks aimed at disrupting European support for Ukraine.

The Danish assessment indicates that Russia is likely to carry out more frequent attacks with greater consequences for targeted nations, including attempts to cripple critical infrastructure. It warns of a low but growing risk of a limited military attack against NATO countries, potentially using false-flag operations to create confusion and sow division within the alliance.6

In contrast, Estonia's Secretary General of the Ministry of the Interior, Tarmo Miilits, reassured that there are currently no indications of a military attack from Russia against any NATO member. He emphasized that while Russia poses a long-term strategic threat, panic should be avoided, as the country continues to seek to destabilize Europe through sabotage and intimidation.35

Miilits pointed to recent incidents, such as an attempted drone attack on Leipzig/Halle Airport, as evidence of Russian intelligence involvement. He noted that cooperation among European law enforcement is crucial in identifying and addressing these threats. The Danish report concludes that while an outright invasion of a NATO country remains highly unlikely, it cannot be entirely ruled out, especially as Russia may view the coming years as a window of opportunity to act against European allies.4

Key Insight
“The Danish intelligence assessment cites a 'low but growing' risk of a limited Russian military attack on a neighboring Nato country, possibly via false-flag operations. Estonia's Miilits urges against panic, noting Russia's long-term strategic threat but no current military intent.”
