Obtain safe passage to conquer the State of Guo
jiǎ tú fá guó
Borrow the resources of an ally to attack a common enemy. After defeating the enemy, use those resources to turn on the ally that lent you them.
Borrowing can be a temporary and friendly act that will be reciprocated. In fact, help is not always repaid and can backfire on the helper as the borrower may later attack the lender.
Jin wanted to conquer the smaller states of Yu and Guo, but knew it will be very difficult while these remained allies.
Jin first started small combats with Guo and bribed the leader of Yu with gifts to allow passage over Guo territory.
Indebted to the larger Jin, Yu helped further as Jin defeated Guo.
The king of Jin then distracted Yu's leader with a hunting trip while a Jin general conquered Yu, as their leader with his best men were away.
In the Korean war, the American army 'borrowed' military bases in South Korea, which they are still using today.
