Sure, if you engage in strategically idiotic wars in places where there is tacit agreement with the other super power that it is ok, that might happen. But it was not actually relevant. The reason the US never invaded the North was because of nuclear weapons. And the reason these wars were thought in strategically irrelevant places like Vietnam and Afghanistan is because of this tacit agreement between nuclear powers. If you are designing an overall grand strategy where you are willing to send 10s of citizens to their death for marginal strategic value, then such a situation might happen. There are however other strategies you can follow. > After the nuke has been deployed, land forces would need to be deployed to take the area cleared by the nuke, and air forces would be required to support those land forces. Great plan to have your infantry walk into the nuclear wasteland.
