Illegal Alien Invasion Question

How is it not an invasion?

Definition of Invasion:

an instance of invading a country or region with an armed force.
"the Allied invasion of Normandy"

an incursion by a large number of people or things into a place or sphere of activity.
"stadium guards are preparing for another invasion of fans"

an unwelcome intrusion into another's domain.
"random drug testing of employees is an unwarranted invasion of privacy"

This meets the second definition. And when did we become a refugee camp instead of a sovereign nation exactly?

But people flooding into a country illegally IS commonly called an invasion. How about you answer my refugee camp question? When did the United States become a refugee camp instead of a sovereign nation?

Refugees. . .is that what you people are calling slaves now?

Giving up on the invasion argument, I see? We are going through an invasion at the Southern border. And worse, it appears coordinated.
