The current GOP presidential candidates really need to go back to school and study American history. In 1797 the United States government signed the Treaty of Tripoli.  It was submitted to the Senate by President John Adams, receiving unanimous ratification from the U.S. Senate on June 7, 1797. It was signed by President Adams on June 10, 1797, and became the law of the land. It provides:

As the Government of the United States of America is not, in any sense, founded on the Christian religion; as it has in itself no character of enmity against the laws, religion, or tranquility, of Mussulmen (Muslims); and as the said States never entered into any war or act of hostility against any Mahometan (Mohammedan) nation, it is declared by the parties that no pretext arising from religious opinions shall ever produce an interruption of the harmony existing between the two countries.
