Recent developments in Ukraine suggest Russian military commanders have exhausted their ability to effectively respond to a Ukrainian escalation in fighting, which is expected any day.

Recent developments in Ukraine suggest Russian military commanders have exhausted their ability to effectively respond to a Ukrainian escalation in fighting, which is expected any day. An influx of 300,000 new soldiers over the winter has done little to improve the fighting of Russian units, and the reported appearance of 1950s Russian tanks near the battlefield confirms Russian materiel is running out. President Vladimir Putin’s bombing campaigns have not broken Ukraine. It is becoming clear, in my view, that the only way he can meet escalation with escalation is by introducing nuclear weapons.

Moreover, during the past 12 months, Putin has laid the groundwork for using a tactical nuclear weapon in Ukraine. He has removed domestic and operational barriers to doing so and has created justifications, fabricated and real, so that his people support him. In speeches and interviews, he has made the case that Russia is under existential attack — a situation, under Russian policy, that warrants the use of nuclear weapons. He has reshuffled his military leadership accordingly, assigning the three generals responsible for employment of tactical nuclear weapons to command his “special military operation” in Ukraine. He already has tactical reasons to explode a nuclear weapon: saving Russian soldiers’ lives, shortening the war, destroying Ukrainian forces. He also has strategic reasons: rejuvenating the deterrent value of his nuclear arsenal and proving that he is not a bluffer.

Putin’s threats have included both strategic nuclear weapons, which can reach the United States, and tactical nuclear weapons, which are generally smaller in explosive power and could be launched from shorter distances to strike Ukraine. His threats include preemptive strikes against those who threaten the survival of Russia. Unlike Ukraine, the U.S. and NATO have their own nuclear weapons to deter a Russian strike. But they have made it clear they will not use their nuclear weapons to defend Ukraine. This leaves Ukraine especially vulnerable to nuclear attack.
