Background: The American Commonwealth
The USA is no longer a legal entity. A popular "statism" movement saw the election of a single-issue president, who legally and peacefully oversaw dissolution of the federal government. All American states are now countries (independent nation-states):
- their governors are now presidents
- the dominant party in each New Country is "nationalist" (does not imply right-wing)
- they are individually recognized by the UN, Olympic Games, etc
- there is no significant political will to re-unite, instead there are shows of goodwill like the "American Commonwealth Games"
- previous agreements and treaties between the USA and other countries are dissolved unless at least one New Country opts-in (multiple opt-ins are allowed)
Which minimal set of states would the Republic of California rely on?
My understanding is that California is not self-sufficient. It relies on other states (now New Countries) for essential resources like water. What is the smallest set of New Countries (and non-US nation-states) that California could/would rely to meet the material needs of her residents?
I've become aware that, for example, California's water needs are not simple and change may be required, so for the purposes of this question I'm happy to focus on resources and needs as they exist now, rather than projections and works in progress.
What political arrangement they come to is obviously a narrative decision, I'm just trying to isolate the material relationships.
