It will be the downfall of our nation.


The civil war and all wars were tragic so I would like to bring your attention to another war in the United States in which our military, our citizens and our children are being betrayed. The war is on the American people by the illegal alien invasion sanction by your government and others.

About 116,353 Americans have been killed by illegal aliens since 9/11 according to figures by Rep Steve King of Iowa who says 25 Americans are killed daily by illegal invaders. About 12 Americans a day are killed by drunk illegal alien drivers who think it's "macho" to drive drunk.
