Did violence solve the Civil War?

I assume that this question is really asking whether violence solved the problems that led to the Civil War.  If this is really the question, the answer is that violence did solve the problems to some degree, but it did not solve them completely.

The major problem that led to the Civil War was the fact that the North and the South distrusted one another and were very different in many ways.  The most important way in which they were different was that the South had slavery and the North did not.  The issue of slavery was clearly solved by violence.  The North could not make the South abolish slavery through political means.  However, it was able to force the South to do so after it defeated the South in the Civil War.  Thus, violence most definitely solved the problem of whether the US would be a country with slavery.

However, the violence did not solve all of the problems that led to the Civil War.  Violence could not make the North and the South trust one another any more than they previously had.  Violence could not make the two regions of the country similar in terms of culture and history.  These problems, in a sense, continue to be with us even up to the present day. 

Violence is able to solve some problems. When all you need to do is force people to change laws or give up territory or something like that, violence can solve problems.  However, violence cannot solve problems that are based mainly in people’s minds.  It cannot change the way people think or feel.  To the extent that it was differences in laws (on slavery) that caused the Civil War, the violence did solve those problems.
