Hmm. . What exactly is the definition of a deployed "strategic" nuclear weapon? As opposed to a deployed "tactical" one?
In the bad old days of the Cold War a city would be the target of at least three, just to make sure. Today one can be lobbed through the town hall window to do the job. Tactical weapon yields are tailored to the target's size and distribution, specifically for use against military formations and no-one is saying how many of
them are deployed.
