Most likely they really want to hit Fort Hood or maybe the Lockheed plant in Fort worth (Home of the F-22 and F-35). But what the hey, Texas is a big place and even they might be able to hit it, sure would hate it if they were to accidentally take out Neuwavo Laredo or Cuidad Juarez.
You might be right. I traced out those lines on a graphics program and it looks like the one is heading either towards Dallas/Ft Worth or Atlanta. Or Oklahoma City? I can’t tell.
For all we know someone just drew some lines on the map to look scary... but we don’t know their thinking. They aren’t rational.
