Alternative Theories and Predicted Empirical Evidence.
| MOTIVES | EMPIRICAL INDICATORS |
|---|---|
| Extended deterrence Russia deploys nuclear weapons to deter adversaries and protect Belarus | Official framing: Russian and Belarusian statements present the deployment as deterring NATO/Western action and protecting Belarus. |
| Military indicators: doctrinal, command-and-control, or posture changes consistent with limited nuclear warfighting. | |
| Credibility costs: evidence of diplomatic and strategic costs, sunk costs, or reduced reversibility that increase commitment credibility. | |
| Assurance Russia deploys nuclear weapons primarily to assure Belarus and strengthen alliance confidence | Official framing: Russian statements depict the deployment as reassuring Belarus and signaling alliance reliability; Belarusian statements portray it as stabilizing. |
| Alliance entanglement: deeper Russian involvement in Belarus’s defense that raises the costs of aggression and signals protection. | |
| Power projection Russia deploys nuclear weapons to increase its own strategic reach vis-à-vis the West | Official framing: Russian rhetoric emphasizes strategic reach. |
| Operational indicators: force posture consistent with forward coercive capability and escalation leverage. | |
| Belarusian alignment: Belarusian rhetoric endorses or echoes claims about expanded Russian leverage. |
