Answer:
A. Pangeans are historically untrustworthy.
Explanation:
The speaker's point of view is most likely that Pangeans are historically untrustworthy. At the beginning of the passage, he states that Pangea has long yearned to possess their resources. That's why he thinks they're likely to attack. Based on the following statements, we can conclude that Pangeans already tried defeating them. He doesn't explicitly state that it was them who attacked (We have never been defeated before - he doesn't say by whom), but based on the context, we can make this conclusion.
The speaker says that his people will defend what is theirs, which means that they will respond to violence by violence. To him, war isn't the last resort for resolving conflict.
Democratic principles are something he obviously treasures (what makes us fair-minded and democratic is our strong national character), and he never says anything about suspending them during wartime.
This is why option A is the correct one.
