No Nukes huh?
The rest of the world would beat the US through shear numbers... and the UK being pretty close to the US in Military tech.
If the Uk sided with the US though... it'd be hard even for the rest of the world to stand up to that conventionally.
They could obviously stalemate because there wouldn't be enough soldiers in the US/UK to invade the rest of the world... or even a large part of the world...
But I'm not sure they could win. As modern technology seems to make numbers more and more worthless.
