Cannot really compare that. Everything is set up now for being included as a state. Going independent would change everything. Frankly having a strong military would be more an issue to keep trade going than anything else. Without it nobody will be hesitant to blackmail those new nations with poor trade deals. Or use force to shut down their economy. 2-3 small strikes on some key power plants and most of California is in the stone age for the foreseeable future.What percentage of the California and Texas Economy is dependent on the Inter-state commerce vs. International commerce negotiated and regulated by the Federal government ?
