When will that call be made to attack the United States from within?
There will be no need to co-ordinate and armed attack from them, as they will just overwhelm us with their numbers. They will overtax the welfare system in each state and drain our resources.
They come from countries where the concept of the rule of law is unknown, so they will bring with them charming practices that will make our native criminals look tame by comparison.
I call them Obama’s Alien Army of Cultural Destruction. The USA will have ceased to exist in 10 years.
