Greetings, I am playing RFC, and recently defended my German colonies against the American uprising. Lincoln is almost dead but recently got 1 city back via congress. This last city has a single warrior (who just got hit by a Cannon) in it. Lincoln has no further units, and iirc his 10 turns limit has passed. Nevertheless, I cant make him capitulate is this options is redded out. I would actually like to vasall him as colonising America as Germany appears to be a tad expensive stab wise (I conquered England and France, Dutch and Portugese are vasalls, only non vasall civs in central europe are Spain and Vikings). Given that I am not treating my other vasalls (Russia, Dutch, Turks, Khmer, Portugal) badly, I cant really see why he would prefer extinction other becoming a vasall and getting large parts of the US.
