Hmm we are not talking about the US here and someone robbing a 7/11 this is a military coup and as long as any of it leaderships is alive there is danger of it continuing.
Of course under those conditions you take what steps you need to take, just as if the plotters had been on the winning side the current government leaderships would had likely been kill.
When a Russian Tsar, who name I can not think of at the moment, was overthrown by his son supporters he was kill and that is the way of the world.
Or in South Veitnam coup that the CIA had a hand in the president and his brother was kill.
