Nigger, the whole point is that I've done that what must be nearly a dozen times already thru out the 15 years the game has been out. A mod that lets you persuade him not only makes more sense from a gameplay perspective since it rewards pacifist players, but it also shows player growth, as you basically force him to sign his own annexation papers AND have him send Securitrons to the damn out of his own free will when the last few ambassadors couldn't even get him to meet, let alone agree to their terms. It's basically a feat similar to talking down Lanius, a man who tells you fills roads in his territory with others who tried to do the same.
