The first step is to cut off the purse strings that bring the invaders to this country. The second is to secure the borders and turn the invaders away. The third is to deport the illegals and the troublemakers.

If the civilized world is to survive, Islam must be understood for what it really is: It's not a religion, form of government, or anything recognizable to the civilized mind. Islam is a disease, an incurable disease of the mind that is highly contagious among the feeble minded and is now spreading among the world's feeble minded at an epidemic rate. As with any disease, one can't reason with this disease, negotiate with it, or treat in any manner other than how one would treat any incurable disease.
As past efforts to contain this disease have failed, carriers of this Plague of Islam must be eradicated wherever they're found, for if they're not, this disease will eventually end not just Western Civilization, but it will undo over 5,000 years of human civilization.
