You're in the Oval Office. Russia has just used a small, tactical nuke on the battlefield in Ukraine. What response do you advocate?
With Russia poised to annex the Ukrainian territories currently under their control and potentially expand their nuclear umbrella to include them, this is becoming an increasingly real possibility. While there are strong arguments for publicly preserving ambiguity about what the response would be, inside the oval office a game plan is needed.
For the purposes of this poll, I am not distinguishing between a 'US' action and a 'NATO' action. You may assume whichever you like.
Another intriguing possibility is a demonstration nuclear strike, on Snake Island for instance. But this time let's assume this is used for military advantage.
If you have a good argument for one or the other, please include it.
