In answer to the second question I did find this:<br/><br/>http://www.startrek.com/boards-topic/33351946/dominion-vs-the-borg<br/><br/>Seems I'm not the only one to speculate regarding that question...!<br/><br/>Personally I think it would be like the Dalek/Cybermen war in the Dr Who series "Destiny Of The Daleks". I think both powers would fight each other to a standstill...<br/><br/>According to Memory Alpha, the Federation spans both Alpha and Beta quadrants, and the Klingon Empire is largely in the Beta Quadrant.
