No, because 98% Californians would oppose sucession and thus overwhelm the other 2%. The illusion that millions of Californians will fight till the death for their "nation" is nonsense. Most Californians, like the rest of the nation, will consider this a terrorist act and thus be pleased with the notjobs being removed from power.
I can't speak for others, but my posts have been written with the assumtion that California would secede through a democratic process(ie popular referendum). I don't believe that Californians would "fight to the death", well because first of all I don't believe it would come to that.
What scares me, is that there are people on this forum who cannot agree to the proposition that California should be able to secede if its people wanted to. The only rational I can come up for these people is that they believe in "America" with some kind of irrational idolic ferver.
I'm usually pretty darned laid back. But these crazy ideas have to be faced with the facts. 
, thunderbolts! anyways, For the sake of practicality, international order, and security, the US would be obliged to reconize California's independance.
You also seem to wonder why the rest of the US population are "Californiaphobes". I've never sensed this. I lived in CA for 2 years, rest of the US much longer. I submit that you may be a self-hating American, trying to raise yourself above the rest of the US. If there are things you don't like about the US, get involved and change them, don't pout and say "Give me my ball (and my large economy), I'm going home."
