On Kable's command, hundreds of vampires got into position. While the other races may be less than normal humans, there were still tens of thousands of each kind. That being said, the strict rule that the Vorn family has upheld about staying in the dark and the on the surface harmony that each race had with one another was to keep an all out war from happening. If such a thing were to actually happen, then many countries or even the world could be turned upside down in a matter of hours. The powers of other races were much greater than even the nuclear weapons that the humans possessed. Their small weapons could not even kill an elven mage who could easily create a barrier around themselves and walk away unscathed or unaffected by the radiation.
