"Let us not call this view reductionist. Jefferson would perhaps have been just as eager to send a squadron to put down any Christian piracy that was restraining commerce. But one cannot get around what Jefferson heard when he went with John Adams to wait upon Tripoli’s ambassador to London in March 1785. When they inquired by what right the Barbary states preyed upon American shipping, enslaving both crews and passengers, America’s two foremost envoys were informed that “it was written in the Koran, that all Nations who should not have acknowledged their authority were sinners, that it was their right and duty to make war upon whoever they could find and to make Slaves of all they could take as prisoners, and that every Mussulman who should be slain in battle was sure to go to Paradise.” (It is worth noting that the United States played no part in the Crusades, or in the Catholic reconquista of Andalusia.)
Ambassador Abd Al-Rahman did not fail to mention the size of his own commission, if America chose to pay the protection money demanded as an alternative to piracy. So here was an early instance of the “heads I win, tails you lose” dilemma, in which the United States is faced with corrupt regimes, on the one hand, and Islamic militants, on the other—or indeed a collusion between them.
It seems likely that Jefferson decided from that moment on that he would make war upon the Barbary kingdoms as soon as he commanded American forces. His two least favorite institutions—enthroned monarchy and state-sponsored religion—were embodied in one target, and it may even be that his famous ambivalences about slavery were resolved somewhat when he saw it practiced by the Muslims.....
There were many Americans—John Adams among them—who made the case that it was better policy to pay the tribute. It was cheaper than the loss of trade, for one thing, and a battle against the pirates would be “too rugged for our people to bear.” Putting the matter starkly, Adams said: “We ought not to fight them at all unless we determine to fight them forever.”
The cruelty, exorbitance, and intransigence of the Barbary states, however, would decide things. The level of tribute demanded began to reach 10 percent of the American national budget, with no guarantee that greed would not increase that percentage, while from the dungeons of Algiers and Tripoli came appalling reports of the mistreatment of captured men and women. Gradually, and to the accompaniment of some of the worst patriotic verse ever written, public opinion began to harden in favor of war.
