That is correct. The thing to watch out for are wars of opportunity, wherein an AI empire sees you as weak (maybe because you are not building ships) and may declare war on you.
Pacifist leaders are the only ones who will never do this. In ROTP, those words describing the leaders have meaning that you can rely on.
For example, Ruthless leaders don’t care if you break treaties or even drop bioweapons. Hey, sometimes you gotta do what you gotta do.
Honorables will never forget an oathbreak, and pacifists will never forget a genocide, whereas aggressives view genocide as just an inevitable consequence of being in their way. Coming in 2.15 this week, Xenophobes will become completely intolerant of spies, even if they are hiding.
