If it does not favor him, then—using treasury and force—he should support his ally and obtain (recruit) kings who hate the Madhyama: either many who stand mutually supported, or many who would succeed together under a single success; or those who, suspecting one another, would not rise. Among them he should secure the principal one, or one nearby, through conciliation and gifts.
A principal provides leadership and coordination capacity; a nearby king offers speed, logistics, and immediate pressure—both maximize coalition effectiveness per unit cost.
