That doesn't really address the question, funds were not given to Iran on a whim, wars were started in the Middle east by Western powers looking to clean up a mess to some extent also created by Western powers. War, people dying and being maimed - those are not linked to one particular event that can be removed from its context and still mean something useful, and the suggestion here that without those particular funds Iran's sponsorship of terrorism would be significantly affected - to whatever extent it can be demonstrated there is any link between those funds and activities - is just random speculation. One state with which the US is not at war offering a bounty for the killing of US soldiers is a different scenario.
