As the war in Ukraine enters a prolonged and costly phase for Moscow, Western analysts warn that the Kremlin is preparing a dangerous escalation of hybrid warfare in Europe, with particular focus on 2026.
An analysis published by the Royal United Services Institute (RUSI), one of the United Kingdom’s most prestigious security think tanks, states that Russia is losing time, resources, and strategic influence, but this decline could make Vladimir Putin’s regime even more aggressive.
“Declining powers often become more dangerous,” the authors note, warning that Moscow is preparing to shift its focus from conventional military fronts to sabotage, disinformation, and political pressure against the West.
From Military Failures to Hybrid Warfare
According to the analysis, Russia has failed to achieve most of its strategic objectives in Ukraine. The Russian military has suffered massive personnel and equipment losses, the economy is under severe strain from sanctions and international isolation, and the regime’s internal stability is increasingly in question.
However, instead of a strategic withdrawal, the Kremlin is expected to pursue hybrid escalation.
“2026 is seen as a window of risk, during which Russia may attempt to compensate for military weaknesses through unconventional means,” the report states.
These means include sabotage of critical European infrastructure, cyberattacks, election interference, and large-scale disinformation campaigns aimed at undermining Euro-Atlantic unity and exhausting Western public opinion.
Although the analysis focuses on Europe as a whole, security experts assess that regions such as the Western Balkans remain particularly vulnerable to Russian hybrid operations due to political polarization, weak institutions, and Moscow’s historical influence.
“In areas where democracy is weak and societies are divided, hybrid warfare works better than tanks,” Western security sources cited in RUSI’s report note.
Diplomatic circles suggest that Russia could exploit elections in some European countries, social tensions, and debates over aid to Ukraine to fuel political chaos and strategic division.
One of RUSI’s main concerns is the lack of a coordinated European strategy to counter hybrid warfare.
“Europe continues to treat hybrid incidents as isolated cases, rather than as part of a consistent Russian doctrine,” the report states.
This, analysts argue, gives the Kremlin confidence to act below the threshold of open warfare without facing serious consequences.
The conclusion of the analysis is clear: even though Russia is losing militarily and economically, the threat it poses to European security remains real and is growing, particularly in the form of hybrid warfare.
“If the West does not establish a credible deterrent against these tactics, what Moscow failed to achieve through military conquest could be pursued through internal destabilization,” RUSI warns.
In this context, 2026 is seen not as the end of the crisis, but as a new and potentially more dangerous phase in the confrontation between Russia and the West./TheGeoPost.
