California, like anywhere else on Earth, should have the right to secede whether the United States likes it or not. The preferences of the other 49 states and Washington DC is not relevant. That was the position of the United States government on Yugoslavia and other places around the world but not on Ukraine. However, morality and the law as I understand it are that any people should have the right to leave, just as explained in the initial words of the US Declaration of Independence. - David Swanson
