While I am sure this has not been overlooked, I'll also reiterate that Morek threatened to punish any aggressive action taken by D'Hara against Luria.
From Luria's (or at least Alanna's) perspective, that exchange went something like:
"So, if D'Hara attacks us, will you declare war on them, too?"
"Well...I hardly think
that's likely to happen. (After all, they're civilized folk, not like you barbarians.) But...all right, I
guess if by some absurd happenstance they declared war on you, we would probably declare war on them, too. (Assuming they didn't have a perfectly good reason to do so. Which I'm sure they would if that ever happened.)"
So...yeah, not exactly filled with confidence.
