In 1784, Thomas Jefferson, John Adams and Benjamin Franklin were commissioned by the first Congress to assemble in Paris to see about marketing U.S. products in Europe.
Jefferson quickly surmised that the biggest challenge facing U.S. merchant ships were those referred to euphemistically as "Barbary pirates."
They weren't "pirates" at all, in the traditional sense, Jefferson noticed. They didn't drink and chase women and they really weren't out to strike it rich. Instead, their motivation was strictly religious. They bought and sold slaves, to be sure. They looted ships. But they used their booty to buy guns, ships, cannon and ammunition.
Like those we call "terrorists" today, they saw themselves engaged in jihad and called themselves "mujahiddin."
Great article on how the founding fathers handled militant Islam. The founding fathers were so smart; and probably half of their brilliance was due to not being hindered by PC thinking.
