Belarus is preparing to impose martial law: what does this mean for Ukraine?

Belarus is preparing legislative changes that would allow martial law to be declared in the event of aggression against Russia, with which the country is a part of the Union State. This creates the risk of Belarus being formally drawn into a war against Ukraine, in particular under the pretext of “protecting an ally” from Ukrainian attacks.

This was reported by the Ministry of Defense of Belarus.

The Belarusian Ministry of Defense officially announced the submission to the lower house of parliament of a bill that provides for the possibility of introducing martial law due to a full-scale Russian war against Ukraine.

The document, entitled “On Amendments to Laws on Ensuring Military Security and Defense,” proposes to expand the list of military threats that may serve as grounds for introducing a special legal regime.

According to the explanation of the Ministry of Defense, such threats may now include strikes by the Armed Forces of Ukraine on military facilities on the territory of the Russian Federation – even if they do not directly concern Belarus.

“The act of armed aggression by any state (coalition of states) committed against the Union State is considered an attack, which is the basis for the introduction of martial law on the territory of the Republic of Belarus,” the document states.

The key argument underlying the bill is the Treaty on the Creation of the Union State, signed between Belarus and Russia in 1999. It provides for close integration, including in the field of security and defense. Thus, the Belarusian Ministry of Defense treats armed aggression against any part of the Union State as an attack on the entire community, which formally paves the way for the introduction of martial law even without a direct attack on Belarus.

The draft law clarifies the functions of the General Staff and the Armed Forces in responding to threats. It also plans to update the military doctrine to include additional conditions for mobilization measures and restrictions on civil rights in the event of escalation.

The initiative of the Belarusian Ministry of Defense appeared against the backdrop of preparations for large-scale joint exercises with the Russian Federation “West-2025”, which are traditionally held with the practice of scenarios of a full-scale war with the West.

At the same time, Ukraine continues regular attacks on military facilities in the Russian Federation — including with drones, missiles, aerial bombs, and raids in border regions. Moscow calls these actions “external aggression.” In this context, Belarus can use the changes in the law as a formal pretext for active participation in the war — by transferring additional resources, logistics, and in the worst-case scenario, manpower.

While Minsk currently refrains from direct involvement in the war, legislative initiatives like this one allow the authorities to legally justify intervention if the Kremlin increases pressure or offers compensation.

By the way, demand for Belarusian defense developments has grown rapidly since the start of Russia’s full-scale aggression against Ukraine. In response to the growing demand from the Russian Federation, the Belarusian authorities have sharply changed their priorities in technology development – instead of civilian areas, projects with military potential have become the focus of attention.

Recall that the Belarusian economy is slowing down due to integration with Russia . In 2025, Belarus’ GDP growth decreased compared to last year.

As reported, Belarusian dictator Alexander Lukashenko cannot keep the economy in check, which is gradually deteriorating . In an attempt to curb inflation, the authorities are once again resorting to price regulation.
