Are you doing nothing?

This rhetorical question is asked sarcastically and means that they should be doing the opposite. This question can be written as a statement. Alternate translation: "You should be acting now!" (See: rc://en/ta/man/translate/figs-rquestion and rc://en/ta/man/translate/figs-doublenegatives)

Do not be slow to attack

These two negative words "not" and "slow" together emphasize the positive idea to attack quickly. Alternate translation: "Hurry! Attack" (See: rc://en/ta/man/translate/figs-doublenegatives)
