Violating our treaty with the GMG of Sigma-13 by moving into their space is reason enough to have them put to death. They are risking our improving relations with Kusari as a whole.
Undermining my glorious military and police forces while flying one of our own ships? This is treason. I believe we all know the punishment for treason?
Here are my orders, however much I hate giving them:
Destroy their ships and bring me any escape pods if they will not surrender and be boarded.
Remember. If they will NOT surrender for trial.
