It's probably not too much of a stretch to assume these guys are Americans. They behave like American stock villains, and HT's nationality suggests that American is the default nationality for a character from our time or even a few decades hence, unless there's some compelling reason to think otherwise.JonathanMarkoff (talk) 09:13, September 24, 2016 (UTC)

"By 2059 the North American Free Trade Agreement had led to a political union of the US, Canada and Mexico. The driving force was the reaction to President Donald Drumpf's failed attempt to build a wall between Mexico and the US leading to the formation of this new nation on July 1, 2022."
