Level 1 - Absolute Beginner

Russia and Belarus did big military exercises together. They practiced using nuclear weapons. This happened from May 19 to 21, 2026.

The leaders of both countries watched the exercises. Vladimir Putin is the leader of Russia. Alexander Lukashenko is the leader of Belarus. They watched on video.

Russia moved nuclear warheads into Belarus. A warhead is the dangerous part of a missile. They also fired two types of big missiles.

NATO is a group of countries that work together for safety. The leader of NATO said that using nuclear weapons would be very bad for Russia.

Level 2 - Elementary

Russia and Belarus held large joint military exercises from May 19 to 21, 2026. The drills were focused on nuclear weapons. More than 64,000 soldiers took part in the exercises.

For the first time, both presidents joined the exercises together. Putin and Lukashenko watched by video link. Russia fired a Yars ballistic missile and a Zircon hypersonic missile during the drills.

Russia also moved nuclear warheads to special storage sites inside Belarus. This was a major step. Over 200 missile launch platforms, 140 aircraft, and 13 submarines were used in the exercises.

NATO's leader, Mark Rutte, responded with a clear warning. He said that if Russia used nuclear weapons, the response from NATO countries would be devastating. Ukraine said the drills were a dangerous signal to the rest of the world.

Level 3 - Intermediate

Russia and Belarus conducted a major joint nuclear forces exercise from May 19 to 21, 2026, involving more than 64,000 military personnel, over 200 missile launch platforms, 140 aircraft, 73 surface vessels, and 13 submarines, eight of which are strategic missile submarines. The exercises were described by Moscow as preparation for the use of nuclear forces in response to aggression.

In an unusual move, President Vladimir Putin and Belarusian President Alexander Lukashenko both participated via video link, marking the first time the two leaders had jointly overseen such a drill. During the exercises, Russia test-fired a Yars intercontinental ballistic missile and a Zircon hypersonic cruise missile, and delivered nuclear munitions to field storage facilities inside Belarus.

The drills come amid heightened tensions between Russia and NATO over the Ukraine conflict and a series of drone incursions in the Baltic region. Kremlin spokesman Dmitry Peskov acknowledged that the exercises were 'a signal', telling reporters that any military drill sends a message about a country's capabilities and readiness.

NATO Secretary General Mark Rutte responded with a firm warning, stating that Russia would face 'devastating consequences' if it used nuclear weapons. Ukraine's Foreign Ministry condemned the move, saying that by turning Belarus into a nuclear staging ground near NATO borders, Russia was setting a dangerous example for other authoritarian regimes around the world.

strategic

relating to long-term military planning or the use of powerful weapons

intercontinental

capable of travelling between continents

munitions

military weapons and ammunition

incursion

an unwelcome invasion into a territory or area

staging ground

a place used as a base from which military operations are launched

authoritarian

demanding complete obedience to authority; not democratic

aggression

hostile or violent action against another country

oversee

to watch and manage a process or activity

Level 4 - Advanced

Russia and Belarus concluded a three-day joint nuclear forces exercise on May 21, 2026, deploying more than 64,000 personnel, 200-plus missile launch platforms, 140 aircraft, 73 surface vessels and 13 submarines -- eight of them strategic missile submarines -- in what Western analysts have called the most expansive nuclear signalling exercise since the Cold War. The drills included the live test-firing of a Yars RS-24 intercontinental ballistic missile from Plesetsk and a Zircon 3M22 hypersonic cruise missile from the Barents Sea, as well as the transfer of nuclear munitions to dispersed field storage sites inside Belarus.

The exercise carried unprecedented political weight: for the first time, Presidents Vladimir Putin and Alexander Lukashenko both participated via video link, a deliberate choreography that signalled shared nuclear custodianship and, by extension, an expansion of Russia's nuclear umbrella over its sole treaty ally. Kremlin spokesman Dmitry Peskov confirmed the drills were 'a signal', framing them explicitly as a message about the Kremlin's preparedness and resolve.

The immediate geopolitical context is a spiral of tensions with NATO triggered by persistent drone incursions over Baltic member-state airspace and Ukraine's accelerating deep-strike campaign against Russian territory. NATO Secretary General Mark Rutte responded by warning of 'devastating consequences', echoing the alliance's long-standing declaratory policy of flexible response while stopping short of specifying thresholds. Ukraine's Foreign Ministry went further, characterising Russia's use of Belarusian territory as a nuclear staging ground as 'de facto legitimisation of nuclear proliferation' that risks emboldening other authoritarian regimes.

The transfer of warheads to Belarus raises thorny questions under the Nuclear Non-Proliferation Treaty and the 1994 Budapest Memorandum, instruments both countries nominally observe. Critics note that Russia's deployment mirrors -- and arguably exceeds -- the scope of NATO's own nuclear-sharing arrangements under Article 4 discussions, creating a symmetry of risk that neither side has explicitly acknowledged. With New START effectively defunct and no successor arms-control framework in sight, the exercises underscore a broader erosion of the guardrails that managed superpower nuclear competition for five decades.
