Question

Based on context clues, choose the best synonym for the word subversion as it is used in this excerpt from President John F. Kennedy's Inaugural Address. assertiveness compliance opposition sabotage

Answer 1

Sabotage

This is best synonym for the word subversion in President John F. Kennedy's Inaugural Address.
To quote: " Let all our neighbors know that we shall join with them to oppose aggression or subversion anywhere in the Americas."
The speaker/writer expresses his allegiance to neighboring countries who may be facing disruption and/or destruction of the country's autonomy as a state.

Answer 2

I think the best answer would be opposition, because
"the act of subverting; as overthrowing"
So the opposite would be compliance but the same would be opposition.
