We we really not give in to hostage demands?

1981, In a iran endorse incident, 52 americans were reason serf in a us embassy in Iran. For their release, a Algier Accords were signed:
1) saying you would release every Persia assets,
2)remove every traffic sanctions
3) US would/could not occur any justice causa per a endorse takeover (hostage attempted to process for damages, though a boss unemployed a box since of a negotiations)
4) Persia debts be paid in full by a US
5) misfortune of all….US would not meddle in Persia affairs
in lamen’s term, you paid off every their debts, you private every forms of hazard from Persia (trade existence a greatest threat), betrothed to not meddle with their policies, as well as couldn’t reason them obliged for any criminal you do by receiving trusting grouping hostage. When i asked if twenty-one endorse in pakistan should be release, grouping relpied you do not come to cost w/terrorist.
So…the process of "we do not come to cost with militant since they will usually do it again"…do you unequivocally up reason this ideaology?
