No. We should annex Canada instead.
I read somewhere that there were plans by a victorious North to invade Canada which had served, during the war, as a conduit point for Confederate soldiers and terrorists to attack various northern cities.
"Terrorists"? Keep fading Frodo, please.
We should just go back to what the founders intended us to be. Strong state governments overseen by a moderately strong federal government who defended the nation in times of distress. I know it's a radical idea but still.
Nice vision, but it's incompatible with the US defending its "interests" all over the world.
