Quote context

[...]

- My brothers, a hasty attempt to outrun the Cylons spawned in the midnight of desperation seems foolhardy in the light of day.

- I propose, instead, we now attempt to appeal for justice and mercy.

- Justice? Justice from the Cylons?

- Is that what you actually said?

- Gentlemen, they've told us that they would not stop until every human had been exterminated.

- Now, why should they believe we are now willing to accept that which we have always found to be unacceptable?

- To live under Cylon rule?

- Because we would destroy our arms to prove we're willing to live in peace.

- Destroy our only means of defense?

- Or attack.

- May I remind my brothers that we did not have conflict with the Cylons until we intervened in their relations with other nations?
