"This Constitution, and the Laws of the United States which shall be made in Pursuance thereof; and all Treaties made, or which shall be made, under the Authority of the United States, shall be the supreme Law of the Land; and the Judges in every State shall be bound thereby, any Thing in the Constitution or Laws of any State to the Contrary notwithstanding."
It's clearly a placating sop to make clear the Barbary War wasn't a "Crusade" but America defending her citizens security abroad. It's not a policy statement, nor do I believe the Senate ratified it as such.
