Lets throw out a hypothetical situation.
You are a US citizen and some “unforeseen” event occurs, an “accidental” chemical release or attack, a nuclear “accident,” or intentional detonation of a nuclear device, another bioweapon. Or perhaps a complete economic collapse, leaving store shelves empty, no fuel/gasoline, the grid goes down, no access to cash, resources non existent, or some other event which forces you and your family to have to migrate cross border IMMEDIATELY. (It is extremely naive to believe that something like this could not happen, especially in this environment).
Biden now finishes Trumps wall, and you cannot get out! Throngs of people now gather at the border, with more coming, desperate to get across to find some kind of refuge. Resources become scarce, other than that which you may have brought with you, food/water. More people arriving, fear, confusion, turns into anger! And people start turning on each other. People with guns start to use them, desperate for resources. Fear, panic, hunger, thirst. The military comes in, takes over, and demands ALL people surrender their weapons. People fight back! Not willing to surrender their weapons, and many people die. FEMA opens “temporary” border camps, and begins to ration food/water as even more people continue to arrive at the border seeking to get out. Quickly, unsanitary conditions manifest themselves, diseases like cholera, dysentery, and typhoid break out- and more people die. Weeks go by, conditions get worse, more sick, dying. On the other side of the border the military digs in, preventing any persons from attempting to cross, except the sick and dying. Temporary field hospitals are overwhelmed, violence explodes. Martial Law is declared and the Constitution is suspended.
You think this can’t happen?
Really?
Yep I sold my mansion and toys in the suburbs few years back and bought a rural cabin on 5 acres. Try to warn people but most don’t listen
Yup.. the border is a roach motel- you can get in, but you cant get back out. Mexico doesn't want to be overrun with Americans- would degrade their culture;)
