You may need headphones for this; the sound's a bit weak.
I believe this what folks of color call "coded humor." Basically Katt Williams is trying make light of the fact that if the US was ever stupid enough to go to war with China, white America would pretty much be on its own.
And that would be one short war.
This comedy special came later, and as we can see, Katt is being a bit more direct here.
