I have an acquaintance who believes that the US as a separate entity no longer exists, which to him is why the southern border is not being enforced, it’s not really there anymore.
Interesting thought.
Kinda like the unmarked troops appearing in Crimea, with a “no reason, no comment” appearance of the Russian flag over parliament. Before anyone knows anything is even happening, the definitive actions are already completed and the rest is just managing consequences.
I’ll chew on that one for a while. No “invasion” if there’s no meaningful border.
