Was a book back in the 80s, one of those silly "what if" sci fi things Called "The Texas-Israeli War:1999" about Texas seceding from the Union (the Israeli part came from both sides using Israeli mercenaries in the war). Not really a very reality based book, but it had some interesting ideas. I've always thought if ANY state in the Union had what it takes to secede and hold it together, it would be Texas. California might have the size and economy to make it alone, but I have serious doubts about the political or social forces necessary to sustain California as an independent nation.
