If North America goes to nuclear winter, and we don't colonoize Mars...

...there should be plenty room in South America.

Now all we have to do is get past MS13, where enemy heads get kicked around like soccer balls, and 7,000 or so landmines in Colombia.

Plenty analogies here. I try not to make analogies cliches. But 'don't look down on your neighbor, going up; you may have to pass them again, going down.' That was a paraphrase.

We either spawned gang violence, or out and out war in central America. And no matter how you feel about cocaine, if you plant land mines, you have to dig them up; or step on them later. Either way, it' 30 years from New York to California by foot. And without conflict, who knows how long it takes to get to the Panama canal from the Mexican border, much less, Argentina, Chile or Peru.
