The U.S. is in the cursed position of having the largest backyard in the world of almost continuous 3rd world nations (Mexico all the way down to Argentina) and no water barrier of any kind to stop them.

Australia, New Zealand, Taiwan, Hong Kong, Singapore, Japan (island nations) and South Korea (via a heavily defended border) are 1st world societies in Asia-Pacific which face no such problems due to their fortunate geography.

In Europe, the Mediterranean provides a great natural barrier from Africa, and nearly all 1st world countries border other 1st world countries (even Germany, which is idiotically letting in so many uncompatible foreigners).

Is there any way we can shift plate tectonics along the Rio Grande and quickly become a US-Canada island continent? It's what we need (and crave).
