Was the fact that the Federation was infiltrated by shapeshifters ever concluded? Presumably they wouldnt be affected by the Virus since they werent in the Link. It also stands to reason that the klingons, Romulans,etc also had shapeshifter infiltrators. With that in mind, it doesnt seem that the surrender is really a surrender, just a method to buy time. The wormhole is reopened so Jem'Hadar ships can come through and shapeshifters have some time to assume some real positions of power. Shouldnt this have been addressed in the last episode?
