A few questions, one of which is better suited to GQ:  
Aside from the issue of cost (billions of dollars) and ill will (it’s a hostile move), what other factors make a US-Mexico border fence a bad idea?  
Second question: The fact that Trump is proposing a fence implies that there isn’t a fence at the moment, so what is at the border at the moment? A line marker boundary? Also, what do most national borders look like - mere signposts?
