Kautilya's Arthashastra 7.6.32

7.6.32

ihāpakārī tyājyaḥ, parāpakārī saṃdheyaḥ, ubhayāpakārī tarkayitavya iti samānam //

But Kautilya says that it is timidity, unprofessional business, and lack of forbearance (to do so). Whoever is injurious to the king's interests should be abandoned, while he who is injurious to the interests of the enemy should be reconciled; and whoever is injurious to the interests of both the king and his enemy should be carefully examined.
