Ukraine

War of 1812 was what some would call a "White Peace". Mostly, status quo antebellum was maintained. The US didn't gain anything but didn't lose either. And the same goes for the UK. After the iniital land victories, the UK was initially going to impose much harsher demands on the US, such as conceding much of the Northwest Territory. The people that "lost" would be the American Indians/Native Americans/First Nation/whatever PC term is nowadays in those territories.
