President Vladimir Putin has repeatedly hinted that Russia might resort to its tactical, or “non-strategic,” nuclear arsenal—estimated at up to 2,000 warheads—if Ukraine or the West crosses a perceived red line. Analysts view a low-yield demonstration over an unpopulated area as the most plausible option.
