I have plans for a space epic and the conclusion to it involves a planet blowing up. The planet was a planet that was taken from the indigenous race and eventually renamed Terrian, a human dictatorship/military planet. It was the home base of the Terrian world government and Terrians spread their militaristic influence to other planets by becoming an ally. However when the planet blew up and after a ruling in the intergalactic relations court Terrians were stripped of their sovereignty due to multiple crimes and no longer having a central base of its leadership outside of Terrian embassies on other planets. Leaving Terrian natives without a technical planet of origin and leaving former Terrian military to be treated as rogue militia or at worst a violent gang. Is this somewhat realistic? Has something like this happened before somewhere?
