"On Saturday, one man held up a sign that said 'Thank You George Bush.'"

Today, there is a new country in the world: South Sudan.

Christian groups had been championing the southern Sudanese since the 19th century. And their efforts paid off in 2000 when George W. Bush was elected president of the United States. He elevated Sudan to the top of his foreign policy agenda, and in 2005, the American government pushed the southern rebels and the central government — both war weary and locked in a military stalemate — to sign a comprehensive peace agreement that guaranteed the southerners the right to secede.
