What if the US took British Colombia because of the Alabama claims?
The UK smashes the USA in the war that follows as sure as night follows from day, the South explodes like a grenade. And this requires Ulysses S. Grant to die from one of the assassination attempts made on him as he was interested in arbitration, not war. Or alternately Andrew Johnson to do something very, very, very, very stupid. If this refers to the UK *selling* this there's the minor issue of Polk settling the USA's Oregon Territory borders decades ago by this point.
