If before (which is what I believe happened):

It sounds and looks like all of the flying castles were in earth's orbit for the last 15 years, why exactly do they need a Casus Belli in the first place

If after:
Why did they even go to war against Earth back then? they are (most likely) a relatively small colony compared to Earth's population and depend on its resources and manpower etc.
They had the super strong technology before the war, and they could have won it had it not been for something that happened on the moon that made them fight for their survival until recently. Now they used the princess's death to legitimize their decent onto Earth instead of unilaterally breaking 15 years of peace.

That's my take on things.
