When we approach Russia-Ukraine War with the perspective of nuclear competition, relentless competition, driven by typical security dilemma, to achieve nuclear superiority is found to be strongly implicated before, during, and after the war. After the post-Cold War order emerged, the U.S. attempted to gain nuclear superiority over Russia by establishing theater missile defense system across Europe. Threat perception coming from the fear of its nuclear deterrence being undermined by America’s damage limitation strategy forced Russia to modernize its nuclear forces and extend the scope of nuclear deterrence to include the possible use of nuclear weapons even against conventional attacks. While Putin raising the prospect of using nuclear weapons invaded Ukraine, the U.S. response seemed to be constrained by the fear of nuclear escalation. Russia-Ukraine War has found 1994 Budapest Memorandum to be nothing more than empty statements and has awakened the world to the reality that nuclear threats are actively being used as a tool of intimation and escalation management. As such, Russia-Ukraine War has ushered us into 'New Nuclear World' characterized by (1) the nuclear paradigm shift from non-proliferation to nuclear competition, (2) retreat of nuclear arms control regime, (3) and tripolar (U.S., Russia, and China) nuclear dynamics.
