In our timeline the southern Chile-Argentina border runs west to east before turning roughly east-southeast to Punta Dungeness, going across the Strait of Magellan, and then south down Isla Grande de Tierra del Fuego to the Beagle Channel. So is there any way to have the border instead continue running east to Cabo Virgenes and then out to sea, preferably with the minimum of fuss? Currently doing some reading about the history of the region but thought I'd see if anyone knew of a quick answer. Thanks.
