दुष्टेषु संधिं दूषयेत् ॥ कZ_०७.१४.०७ ॥
duṣṭeṣu saṃdhiṃ dūṣayet
Among the wicked/unreliable, one should corrupt or spoil the treaty (i.e., prevent or break their settlement).
Kautilya assumes unreliable actors use peace instrumentally; preventing their consolidation can be safer than allowing a stable hostile alignment to form.
