the day the earth stood still

Was Klatu being fair with his demands on earth? Were his actions justified?
I believe that Klatu was fair with his demands. He talked about how the people of earth were foolish and violent. He also spoke of how wars are not good for anyone. Obviously he was scared for his planets well being and safety. If I were in his position, i would be too. So the only thing that he could do to protect his planet was to threaten ours. His actions are justified by the predicament that he was in. He saw a threat and knew that he needed to eliminate it.
