Despite my knee jerk reaction that such a union would be plain wrong, are there any arguments that the joining would be beneficial in any way ?
Not really. In purely economic terms, even a union with Canada would be a problem. They have natural resources and an educated workforce, but culturally they are more accustomed to government “over-reaching” than we. Mexico has oil, and tequila. That’s about it. Bad idea.
Oh, sure! Join with socialist canada and practically anarchist mexico. Drag 2 foreign languages (at least) in here. But it will save money on border guards and fences and stuff like that. Good stuff!
Yup....beneficial to the NWO and the Anti-Christ’s one world government.
