SISKO: Do you know what the trouble is?
SISKO: The trouble is Earth.
SISKO: On Earth there is no poverty, no crime, no war. You look out the window of Starfleet headquarters and you see paradise. Well, it’s easy to be a saint in paradise, but the Maquis do not live in paradise. Out there in the Demilitarised zone, all the problems haven’t been solved yet. Out there, there are no saints, just people. Angry, scared, determined people who are going to do whatever it takes to survive whether it meets with Federation approval or not.
KIRA: Makes sense to me.
SISKO: I’m glad someone understands.
