Answer:
I was not surprised by the history of the USA in the 70s.
Step-by-step explanation:
I cannot deny that the 1970s promoted surprising events and happenings in the USA, such as the withdrawal of US forces from Vietnam, the resignation of President Richard Nixon, the New York blackout, among other events. However, in general, the history of the USA in the 70s does not surprise me, because surprising events must occur in surprising, living and constantly evolving nations.
If great situations do not occur in the history of a country, it is because that civilization is doomed to disappear. As we know the USA is one of the most influential countries in the world, if not the most influential, so it is normal that great situations occur at any time in its history.
