Countries that experienced mass events like wars, natural disasters, disease and others tend to develop a more tight community and sense of nationalism.

My thinking is that because the newer generation didn't experience those events the whole country can't sustain their old morals and culture and begin to ruin under the transition of power because those countries were successful because of that values.

My question is, how can the older generations transfer the lessons learned to people that will never experience nothing close of what they did?
