Mob. Caravan. Invasion force. When a million come at one time the powers that be will throw up their hands and say that the only solution is to open the borders and tear down the barriers. These facilitators are the first ones to be rounded up and deported or worse. The future does not look bright. Load up on guns and ammo and have an exit strategy. What we need is divine intervention.
A more rational response is machine guns at the border. They would only have to be used once.
