"Elitists in the United States, Mexico, and Canada are plotting to merge these three nations into a single regional government similar to the European Union. [Yet] the U.S. and Mexico are separated by language and have fundamentally incompatible political systems... the USNA would likely be held together only through corrupt alliances among ruling elites, backed by undisguised force... Mexico is ruled by a political establishment intimately connected to that nation's narco-terrorist syndicates..."

So...where is the "incompatibility"?
