I recall that someone once said “The Constitution is not a suicide pact”.
That pretty much sums up my view as to whether or not a state has the right to seceed.
”Now, we believe and maintain that the Union is to be preserved only so long as it is beneficial and satisfactory to all parties concerned.
“We do not believe that any man, any neighborhood, town, county, or even State, may break up the Union in any transient gust of passion; we fully comprehend that secession is an extreme, an ultimate resort--not a constitutional, but a revolutionary remedy.
“But we insist that this Union shall not be held together by force whenever it shall have ceased to cohere by the mutual attraction of its parts."
