In a major update to its nuclear strategy, Russia has officially declared that it will protect its close ally Belarus under its nuclear umbrella. This means that if Belarus faces an attack, Russia could use nuclear weapons to defend it. This decision is part of an agreement with the Collective Security Treaty Organization (CSTO), a group of six countries led by Russia, which also includes Armenia, Kazakhstan, Kyrgyzstan, Tajikistan, and Belarus. The announcement comes after a special meeting of the CSTO’s leaders in Astana, Kazakhstan, on November 28, 2024.

Why Is Belarus Getting Special Protection?
Russia has always been committed to defending its CSTO allies, but this is the first time it has specifically mentioned Belarus in its nuclear doctrine. Belarus is particularly important to Russia because the two countries share a close political and military relationship, known as the Union State. This bond is so strong that Russia has already stationed tactical nuclear weapons in Belarus earlier this year.
Russian Security Council Secretary Sergei Shoigu explained that the updated nuclear doctrine makes it clear that Russia will use nuclear weapons to defend Belarus if it’s attacked with conventional weapons or if the country’s very existence is threatened. This is a significant change because, before this update, Belarus was simply covered by the CSTO’s general defense pact but was not explicitly mentioned in Russia’s nuclear policy.
A Close Partnership Between Russia and Belarus
Belarusian President Alexander Lukashenko has welcomed this move, calling it a step that was “long overdue.” Belarus has long been a loyal ally of Russia, and the two countries share a deep connection that goes beyond just military defense. This new nuclear protection solidifies that bond even further, making Belarus a critical part of Russia’s defense strategy in the region.
The CSTO: What Does It Mean for Its Members?
The CSTO is like a defense pact, similar to NATO, where if one member is attacked, the others must come to its aid. However, not all members are equally committed. Armenia, for example, has shown dissatisfaction with the CSTO, as it did not receive support during the recent Nagorno-Karabakh conflict with Azerbaijan. Despite this, Armenia has not officially quit the organization.
For now, the CSTO remains a crucial part of Russia’s military influence, with Belarus being the most important member. The alliance allows Russia to strengthen its presence in the region, especially as tensions grow with Western powers.
Putin’s Hypersonic Weapons and What’s Next
In a separate statement during the same meeting, Russian President Vladimir Putin highlighted the country’s growing military power, particularly the “Oreshnik” missiles. These missiles are so powerful that Putin claimed a strike from several Oreshnik missiles could have the same effect as a nuclear explosion. While these missiles aren’t officially nuclear weapons, their destructive power is incredibly high. Putin boasted that the Oreshnik is unique and has no equivalent anywhere else in the world.
Putin also hinted that Russia might use these missiles against Ukrainian targets, such as decision-making centers in Kyiv. The threat of these missiles, combined with the deployment of nuclear weapons in Belarus, signals a sharp increase in military tension in the region.
What Does This All Mean for Global Security?
With Russia increasingly tying Belarus into its military plans, the potential for conflict in the region could escalate. While the United States has said that it wasn’t surprised by Russia’s actions, this shift in Russia’s nuclear doctrine is still a powerful message to the West. It shows that Russia is willing to extend its nuclear capabilities to protect its allies, particularly Belarus, and is rapidly advancing its hypersonic weapons technology.
This move could change the balance of power in Eastern Europe and beyond, as it demonstrates Russia’s readiness to escalate military responses and expand its nuclear influence. The world is watching closely to see how other countries, especially NATO members, will respond to these new developments.
In conclusion, Russia’s decision to protect Belarus with nuclear weapons and its display of new, powerful missile technology makes it clear that tensions in the region are rising. The future of the CSTO, the role of Belarus, and the implications for global security remain uncertain, but one thing is for sure: the stakes have never been higher.
