I got the impression that Praetoria still has a population of at least a billion or two. There's references made to the Imperial Defense Forces fighting across the world in various remaining DE hotspots, to say nothing of nations that may have told Cole to go to hell. It was noted that a lot of nukes were thrown at Hamidons armies, for example. What makes them so dangerous is the fact that, not even counting Powers Division, the IDF are well trained and experienced, not to mention things like the War Walkers and Warworks. Primal Earth, meanwhile, is rather divided, with lots of nations, terrorist groups, would be world conquerers and the like to make a coordinated defense difficult. Not to mention we still haven't seen just how well Earths militarizes have recovered from the Rikti War.
That said though... Portal Corp and Longbow completely misread what they were seeing with Praetoria originally, seeing it as evil!CoH. Who's to say that Praetoria hasn't made a similar mistake?
