Here's the one specific to the issue at hand:

Article 4, Section 4,

"Section 4 - Republican Government. The United States shall guarantee to every State in this Union a Republican Form of Government, and shall protect each of them against Invasion; and on Application of the Legislature, or of the Executive (when the Legislature cannot be convened) against domestic Violence."

As far as Who decided it was an invasion. . . . I did. Me. A Natural born american citizen. Want someone to blame? Blame me.

It's an invasion.

Want to know why?

People coming into someone else's country, UNINVITED, and AGAINST THEIR LAWS, and marching under foreign flags is the book definition of "Invasion."

I want the US military on the border because Article 4, Section 4 of our Constitution REQUIRES the federal government to protect each state from invasion.

Let me go even farther: I want our Military to use LETHAL FORCE against anyone attempting to storm the border, whether they are men, women, children, or women carrying babies in their arms. I want the military to shoot, to shoot first, and shoot to kill.

I am sick to death of having entire neighborhoods of towns and cities in this country, turned into filthy, violent, crime-ridden, third-world garbage dumps by people who have no idea what it is to BE an "American" and worse, have no desire whatsoever to actually BECOME an American.

Hell, more than half of the ones already here refuse to even learn the English language.

These people have no aspirations about liberty or personal rights. They come to work. They come to get money and send that money OUT of my country to somewhere else.

By having these people filtering-in for decades, it has raised the cost of housing (supply and demand) lower the wages of working class people (supply and demand) and put unimaginable strain on our resources (Health care, water supplies, garbage dumps and more).

I want these "migrant caravans" kept OUT.

Is that clear enough for you?
