If Quebec is included in the USA then there strongly would be more tolerance of Catholics and non-English speakers. This could also foster pan-Americanism as Latin American countries could join the US no problem. @Militant_Ape
Well, I don't know if I would go as far to say Latin America, but there certainly might be more of an appetite for all of Mexico along with Cuba & Puerto Rico (even the Philippines) under such a scenario as I proposed.
