Find a way for American President James Buchanan to prevent the Civil War during the Secession Crisis in 1860.
He accedes peacefully to southern secession, signing a treaty of recognition and thus avoiding war.
Seriously, man was a timid and pitiful figure who had no steel of resolve in him.
This. One wonders what Lincoln would (or could) have done if Buchanan's administration had immediately recognized the seceding states as independent and signed a treaty or treaties recognizing this - which also might reasonably have established a mechanism for the Southern States to purchase federal property. This is very unlikely, but if it occurred I seriously doubt that Lincoln would have the political power to revoke these agreements, which would clearly constitute blatant aggression in the eyes of the "international community", ie: Britain and France.
