Don't worry about the krogans: They don't have spaceships so they can't move and even if they develop their own ships the other of the races are aware about what happened with the krogan rebellions so the krogan are doomed if they try to attack a single colony. It's not the same to start a war having your bases and equal military strength than starting a war without ships agains an enemy (the salarians at least) with it's full military power.
