lets try to stay away from how is this possible(but if that is what you want to do I'll go with it) and agree that it probably requires pods to make the American Army and Navy stronger, the British crueler, more incompetent, weaker, over extended, and more willing to give up in the right circumstance. What I want to know is how it would be the development of this us.
p.s. I also forgot to throw in the Mosquito Coast
p.s. There are two other scenarios one is if Great Britain took all of France's Caribbean holdings as well Canada in the Seven's years war, and I am well aware that pod's required. The third option is like option two but GB took Cuba off from Spain as well Florida. these scenarios could also be a pod required to have the US is luckier, has more resources while the opposite being true for GB,
