Lord P'd'k'tag, 90% of the enemy fleet is in position.
Don't let the T'okjith blow just yet. We want to get every last one of them. The simultanious annihilation of their entire fleet is an event that will indelibly etch our supremacy in their minds should they think to try attacking us again.
Uh-oh... They just teraported out of the system... Every last one of them.
Do you think that narrowly escaping with their lives will indelibly etch our supremacy in their minds?
It doesn't send the same message, no.
