It's debatable whether the order would have been carried out had Kirk's demands not been met. However, would a single Constitution-class ship really have the means to carry out such an order?
I haven't seen anything that suggests the Enterprise has that kind of firepower. There is a similar concept in the Star Wars universe called Base Delta Zero, but completely melting a planet's surface wouldn't be necessary to wipe out all life.
