Do you think we are on the verge of a radically changed government?

in history events that caused national despair was used to further political agendas,that wouldn't work during good times.seems almost every oppressive government took control of country's when a serious national disaster happened,the tell people to follow them and they will lead them to safety and prosperity,when a lot of times those bad events were engineered to make the population more receptive to their political aime,an example was the rise of hitler and stalin and Napoleon,are we at the junction of deciding to leave the bill of rights and Constitution behind and adopting an alternative government?.
