Stardate 51721.3: Captain Sisko records a personal log in which he lays out the mistakes he made in his attempt to change the course of the war with the Dominion. Two weeks ago, in order to put the all the powers into position, he decides that the Romulan nonaggression treaty with the Dominion will have to be annulled so that the Romulans will join the Federation and push the Domonion out of the Alpha Quadrant once and for all.
When the Cardassian occupation of Bajor ended in 2369, the mining space station Terok Nor was left abandoned, its systems ripped out. By invitation of the Bajoran provisional government, Starfleet stepped in to oversee the rebuilding and day-to-day operations of the newly christened Deep Space Nine.
The years of Starfleet's nonintervention into Cardassian matters, however, had taken its toll on relations with the Bajorans. Consequently, Starfleet's position was a tenuous one; many Bajorans, suspicious and hostile as a result of decades of Cardassian oppression and brutality, did not greet the Federation's presence with open arms. The Federation's assistance is put to the test as DS9 becomes a center of travel and commerce that stretches into the Gamma Quadrant.
