Let's assume for a second that this could happen. Then, assuming no foreign alliances, the US could simply conquer California back. CA has the largest contingent of military personnel by state (about 190k) but not per capita. The size of the brave population is actually small compared to the population of the free and it's likely most of them will swear allegiance to the US. And it's not like all of the sudden a lot of free people from the large, typically peaceful cities in CA will all of the sudden find the courage to fight. Historically, outside of the military and rural areas, CA is not known to be a land of fighters (like, say, Texans).
