And even if we did think of using it, just what, three modern nukes would pretty much blanket the entire UK in lethal radiation whilst taking out all major cities.
No, initiating even a one megaton nuclear device in London would not leave much of London intact. On the other hand, the UK would be attacked by several hundred devices, and the attack doesn't need to kill everyone, only to destroy the society, which is much easier.

As an American, I would likely just hide in the mountains and just keep away from the war. Why? Chinese invasion. While the US and Britain are fighting, if the US does go full out (excepting nukes), that would leave the entire West Coast unguarded.
China cannot invade the US, or anyone else it does not share a land border with, as it has no deep water navy. But, yes, there should be an option for "support the UK/US after one week when both sides are crippled"

All I can say is that I bet our nuclear subs are probably hiding near the UK (as well as who knows how many other places). So... if anything happened, a few missiles could get launched before any sort of other attack even took place.
Wouldn't matter if they were, silos based missiles are quite capable of immediately destroying the UK as a nation. On the other hand, the UK also has this ability (IIRC, they also have to have a quicker response time, as missiles from the USSR would arrive earlier, their procedures were created with that in mind).

We have enough missiles and counter measures to knock them out of the sky, still wouldn't be pretty, still.
As I understand it, the US has sufficient counter measures to ensure the majority of potential targets survive, but it wouldn't take many successful attacks to destroy the US society.
