John Quincy Adams, that is. A few quotes from the sixth president:
“…he [Muhammad] declared undistinguishing and exterminating war, as a part of his religion, against all the rest of mankind…The precept of the Koran is, perpetual war against all who deny, that Mahomet is the prophet of God.”
“The vanquished may purchase their lives, by the payment of tribute.”
“As the essential principle of his faith is the subjugation of others by the sword; it is only by force, that his false doctrines can be dispelled, and his power annihilated.
They [The Russians] have been from time immemorial, in a state of almost perpetual war with the Tatars, and with their successors, the Ottoman conquerors of Constantinople. It were an idle waste of time to trace the causes of each renewal of hostilities, during a succession of several centuries. The precept of the Koran is, perpetual war against all who deny, that Mahomet is the prophet of God. The vanquished may purchase their lives, by the payment of tribute; the victorious may be appeased by a false and delusive promise of peace; and the faithful follower of the prophet, may submit to the imperious necessities of defeat: but the command to propagate the Moslem creed by the sword is always obligatory, when it can be made effective. The commands of the prophet may be performed alike, by fraud, or by force. Of Mahometan good faith, we have had memorable examples ourselves. When our gallant [Stephen] Decatur ref had chastised the pirate of Algiers, till he was ready to renounce his claim of tribute from the United States, he signed a treaty to that effect: but the treaty was drawn up in the Arabic language, as well as in our own; and our negotiators, unacquainted with the language of the Koran, signed the copies of the treaty, in both languages, not imagining that there was any difference between them. Within a year the Dey demands, under penalty of the renewal of the war, an indemnity in money for the frigate taken by Decatur; our Consul demands the foundation of this pretension; and the Arabic copy of the treaty, signed by himself is produced, with an article stipulating the indemnity, foisted into it, in direct opposition to the treaty as it had been concluded. The arrival of Chauncey, with a squadron before Algiers, silenced the fraudulent claim of the Dey, and he signed a new treaty in which it was abandoned; but he disdained to conceal his intentions; my power, said he, has been wrested from my hands; draw ye the treaty at your pleasure, and I will sign it; but beware of the moment, when I shall recover my power, for with that moment, your treaty shall be waste paper. He avowed what they always practised, and would without scruple have practised himself. Such is the spirit, which governs the hearts of men, to whom treachery and violence are taught as principles of religion.” [p. 274-275]
