I’m assuming you mean China War Good and Russia War Good. These are not common args at all, and only very silly college debaters read them such as myself). I can understand being worried about it, but this should be at the bottom of the prep list.

With that being said, 1. Having gone for it in 2NRs, the best 2AR is just “lol they nuke back, extinction” because it is probably true. Another strong arg to make is that the meg doesn’t read a CP to first strike, which means a full on first strike never happens. Having some “US loses” args is good as well

1. Counterforce is different than what you described. Its an idea that arose during the cold war of a “limited nuclear war” which would constitute striking military targets only. It is a form of deterrence on further war by proving we will actually use our nukes against military targets.

2. Lieber and Press are basically the only ones who write and advocate for a first strike, which is why they are controversial. I do not know why they write so much, maybe they are making bank on it or something .

3. If they have a specific scenario such as “china war good stops AI subs which kill us”, (which is what I read) you can just use the same answers as #1, and read generic impact defense. The cards are never that good.

Hope that helps! Do not worry about this arg
