I wonder whether the terran if united is in fact the strongest race in the Koprulu Sector?Bcoz,they always engage in petty quarrels that end up in terran civil wars.They seem to pay more attention killing each other rather than Zerg not to mention ProtossBesides how come Protoss and Terrans hardly engaged in battle?
Because Terran and Protoss are highly civilised and could negotiate. The only way to negotiate with a Zerg specimen is to pulverize it.
No, the zerg could easily desimate the remaining terrans if Kerigan wanted to (sheer numbers and all that). She just hasn't attacked, for reasons that will be explained in Starcraft 2. The protoss don't have the numbers and resources to really go at it with the terran, but they still probably have ships that can obliterate planets. The terran could beat the protoss by nuking the hell out of Sakuras If the entire terran race declared war on the zerg and protoss, however, they could probably win. That is, of course, assuming earth has massive fleets somewhere.
