Star Wars Vs Star Trek

Ok, so one day an Imperial Star Destroyer is patroling its usual route when it is swallowed by a GASW (Giant Ass Space Worm) and spat out in the Star Trek galaxy. It is during DS9. The Captain, being non-sucidal, decides that since there is no way back they should try and hook up with some major power.

What powers do you think the Star Destroy would end up allied with/taking over?

Not a typical Vs debate, I admit but it was the best I could come up with on such short notice and I felt that we could use some more threads around here.
