Belarus

Unlikely (roughly 35%) that Belarus will be directly involved in significant armed conflict within the next three years, but the risk is materially elevated by its role as Russia’s military rear area and potential NATO-Russia escalation pathways.

Most likely outcome is continued non-belligerent posture: Belarus provides basing, logistics, and signaling value to Russia while avoiding overt entry into the war. Key watch items are scale/composition of Russian deployments during exercises and any resumption of cross-border strike activity from Belarusian territory. Ukraine’s long-range strike tempo is the main near-term escalation channel.

Over five years, risk tracks the trajectory of the Russia-Ukraine war and Russia-NATO relations more than Belarus’s domestic politics. If a durable ceasefire reduces Russian operational demand, Belarus’s direct-war risk falls. If Russia reconstitutes forces and confrontation with NATO hardens, Belarus’s role as a forward platform increases the chance it becomes a direct battlespace or target, even without Minsk seeking war.

Threat drivers Belarus is structurally exposed because Russia uses its geography for strategic depth against Ukraine and NATO’s eastern flank. Russian military access, air defense integration, and reported nuclear-related signaling increase the chance Belarus becomes a launch, staging, or targeting area in a wider confrontation. Large exercises (e.g., Zapad) and recurring readiness inspections can mask force movements and raise misperception risk. If Ukraine expands long-range strikes, Belarusian military infrastructure used for Russian operations becomes a more plausible target set.

Resilience and stabilizers (pre-mortem) The regime prioritizes survival and internal control; it has strong incentives to avoid a discretionary war that could fracture elites, trigger unrest, or invite direct retaliation. Belarus’s armed forces are assessed as limited in manpower, modern equipment, and independent offensive capacity, reducing the likelihood of a Belarus-led campaign. NATO’s conventional and nuclear deterrence, plus the high escalation costs of crossing NATO borders, functions as a systemic firebreak against deliberate Belarus-NATO kinetic conflict.

Systemic firebreaks The most probable pathway to Belarusian direct involvement is not Minsk’s choice but escalation dynamics between Russia and Ukraine/NATO. As long as Russia remains heavily committed in Ukraine and constrained in reconstituting large conventional formations, the probability of opening a new major front from Belarus is reduced. Diplomatic probing and limited economic re-engagement signals also modestly support continuity rather than rupture.

Net assessment Risk is best framed as alliance exposure and geography-driven entanglement. Direct Belarusian entry into major combat remains less likely than not, but Belarus is a high-value enabling platform; if the wider war expands, Belarus is one of the first places where “support role” could convert into direct kinetic involvement.
