It's hypocritical to think otherwise.
Nothing there says that the British don't have the concurrent right to put down the rebellion.
As long as they realize that success means that they've simply taken the rebels as hostages.
If that's the way you really feel, I look forward to seeing on the news that you've launched your rebellion. Until then, I can only conclude that you either:
a) don't think it's actually that bad, or
b) don't have the gumption to do anything about it.
That's like saying the police should know that the bank robbers they've apprehended are simply hostages.
Rebellion is, by definition, an illegal act. Suppressing rebellion is halting the law breaking. Punishing the rebels is simply doing justice.
