Next, Trump needs to send Mattis to Mexico to outline how the US will seize lands on the Mexican side of the border if Mexico does not get control of its citzens and guests. They need to stop all illegal cross border traffic, else we will do it for them. Time to play hardball.
Ask for forgiveness rather than permission.
Take the territory and then negotiate it;s return
I like it, send Blackjack Mattis to Mexico... excellent idea.
GREAT idea! Since the Rio Grande is a YUGE problem (since you can’t build a wall down the middle of a river), just seize the land on the Mexican side and build the wall there! (never happen, but fun to think about)
