What did Ayatollah Ruhollah Khomeini do to the Carter administration?

lately some agency new such as BBC Persian wanted to distribute a distorted text to Ayatollah Khomeini based on a secret message between him and carter. but according to confident sources the history is not such a way that BBC agency news narrated it. in other word I think that not only, as BBC claimed, Imam Khomeini in response to Carter , alert him on the right of Iranian people in respect to their destiny but also Imam Khomeini try to show Carter, if he threat Iran again this action could followed by serous response by Iranian people.
