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.

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.
