What makes history important in solving problems today is the fact that many things that happened in the past are similar to things that are going on today. When faced with problems of the types that you mention, we can often look to the past for help. We can try to identify times in history when we faced issues that are similar to those we face today. We can look at how we handled things in the past and we use that experience to help figure out what to do about things today. Sadly, this is not a fool-proof exercise and we cannot guarantee that we will solve our current problems through the use of history.
