Origin of laws and belief agaist the U.S.A. and Christianty. The only country to date that openly has powerful factions that verbaly state they will destroy the U.S.A.
LYBIA: Bordering the country of Chad mentioned above, they have publically known HUMAN SLAVE MARKET, no government and terrorist breeding ground. Election issues, riots, religious clashes and killing Christians.
SYRIA: Longest running war and terrorist breeding ground
SOMALIA: Too much to list about Somila. This is a terrorist breeding ground for decads. Human rights violations too disgusting to imagine. Genicidal factions constanly rising and fighting each other.
