It is widely believed that Russia’s large nuclear arsenal is one of the main reasons why Western partners fear the potential collapse of Russia. If Russia were to actually disintegrate, there is a serious risk that regions previously under its control could maintain authority over nuclear weapons. This, in turn, creates a huge threat to global security. Countries sharing borders with Russia are concerned that these regions might start pursuing their own policies regarding nuclear weapons control, potentially causing instability.
This is one of the main reasons why the U.S. and other Western nations are trying to prevent Russia from undergoing deep political changes that could lead to chaos. Currently, the key issue is ensuring control over nuclear weapons and preventing them from falling into the hands of unpredictable actors.
