John Quincy Adams wrote:

In the seventh century of the Christian era, a wandering Arab of the lineage of Hagar [i.e., Muhammad], the Egyptian, combining the powers of transcendent genius, with the preternatural energy of a fanatic, and the fraudulent spirit of an impostor, proclaimed himself as a messenger from Heaven, and spread desolation and delusion over an extensive portion of the earth. Adopting from the sublime conception of the Mosaic law, the doctrine of one omnipotent God; he connected indissolubly with it, the audacious falsehood, that he was himself his prophet and apostle. Adopting from the new Revelation of Jesus, the faith and hope of immortal life, and of future retribution, he humbled it to the dust by adapting all the rewards and sanctions of his religion to the gratification of the sexual passion. He poisoned the sources of human felicity at the fountain, by degrading the condition of the female sex, and the allowance of polygamy; and he declared undistinguishing and exterminating war, as a part of his religion, against all the rest of mankind. THE ESSENCE OF HIS DOCTRINE WAS VIOLENCE AND LUST: TO EXALT THE BRUTAL OVER THE SPIRITUAL PART OF HUMAN NATURE (Adams's capital letters)… Between these two religions, thus contrasted in their characters, a war of twelve hundred years has already raged. The war is yet flagrant… While the merciless and dissolute dogmas of the false prophet shall furnish motives to human action, there can never be peace upon earth, and goodwill towards men."

Lord Tebbit wrote:

"The Muslim religion is so unreformed since it was created that nowhere in the Muslim world has there been any real advance in science, or art or literature, or technology in the last 500 years"

Vernon Richards wrote:

"The true Islamic concept of peace goes something like this: "Peace comes through submission to Muhammad and his concept of Allah" (i.e. Islam). As such the Islamic concept of peace, meaning making the whole world Muslim, is actually a mandate for war. It was inevitable and unavoidable that the conflict would eventually reach our borders, and so it has."

Andre Servier, 1922 wrote:

“Islam was not a torch, as has been claimed, but an extinguisher. Conceived in a barbarous brain for the use of a barbarous people, it was - and it remains - incapable of adapting itself to civilization. Wherever it has dominated, it has broken the impulse towards progress and checked the evolution of society.”

Theodore Roosevelt wrote:

“The Greeks who triumphed at Marathon and Salamis did a work without which the world would have been deprived of the social value of Plato and Aristotle, of Aeschylus, Herodotus, and Thucydides. The civilization of Europe, America, and Australia exists today at all only because of the victories of civilized man over the enemies of civilization, because the victories stretching through the centuries from the days of Miltiades and Themistocles to those of Charles Martel in the eighth century and those of John Sobieski in the seventeenth century.”

“During the thousand years that included the careers of the Frankish soldier and the Polish king, the Christians of Asia and Africa proved unable to wage successful war with the Moslem conquerors; and in consequence Christianity practically vanished from the two continents; and today nobody can find in them any "social values" whatever, in the sense in which we use the words, so far as the sphere of Mohammedan influence. There are such "social values" today in Europe, America, and Australia only because during those thousand years the Christians of Europe possessed the warlike power to do what the Christians of Asia and Africa had failed to do - that is, to beat back the Moslem invader.”

David Selbourne – The Losing Battle with Islam:

"Of course, there are distinguished precedents even for the bleakest and coarsest of these judgements. To Montesquieu in 1748, Islam’s ‘destructive spirit’ spoke ‘only by the sword’; to Schopenhauer in 1819, the Koran was a ‘wretched book’ in which he had ‘not been able to discover one single idea of value’; to De Tocqueville in 1843, Islam was ‘deadly’, ‘to be feared’ and a ‘form of decadence’". –

Winston Churchill, wrote in 1899:

“The religion of Islam above all others was founded upon the sword … Moreover it provides incentives to slaughter, and in three continents has produced fighting breeds of men – filled with a wild and merciless fanaticism”.

John Quincy Adams who wrote in 1829:

"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".

John Wesley (1703-91) who wrote,

"Ever since the religion of Islam appeared in the world, the espousers of it...have been as wolves and tigers to all other nations, rending and tearing all that fell into their merciless paws, and grinding them with their iron teeth; that numberless cities are raised from the foundation, and only their name remaining; that many countries, which were once as the garden of God, are now a desolate wilderness; and that so many once numerous and powerful nations are vanished from the earth! Such was, and is at this day, the rage, the fury, the revenge, of these destroyers of human kind".

Hilaire Belloc who wrote in 1938:

"Will not perhaps the temporal power of Islam return and with it the menace of an armed Mohammedan world, which will shake off the domination of Europeans -- still nominally Christian -- and reappear as the prime enemy of our civilization? The future always comes as a surprise, but political wisdom consists in attempting at least some partial judgment of what that surprise may be. And for my part I cannot but believe that a main unexpected thing of the future is the return of Islam".

Bishop Fulton J Sheen who wrote in 1950:

"Today (1950), the hatred of the Moslem countries against the West is becoming hatred against Christianity itself. Although the statesmen have not yet taken it into account, there is still grave danger that the temporal power of Islam may return and, with it, the menace that it may shake off a West which has ceased to be Christian, and affirm itself as a great anti-Christian world Power".

Patriarch Cyrus of Alexandria, while negotiating the surrender of Alexandria to the Muslims, 640 AD:

"I am afraid that God has sent these men to lay waste the world".

Gregory Palamus of Thessalonica, 1354:

"For these impious people, hated by God and infamous, boast of having got the better of the Romans by their love of God…they live by the bow, the sword and debauchery, finding pleasure in taking slaves, devoting themselves to murder, pillage, spoil…and not only do they commit these crimes, but even — what an aberration — they believe that God approves of them. This is what I think of them, now that I know precisely about their way of life.".

William Eaton, US Consul to Tunis, wrote in 1799:

"Considered as a nation, they are deplorably wretched, because they have no property in the soil to inspire an ambition to cultivate it. They are abject slaves to the despotism of their government, and they are humiliated by tyranny, the worst of all tyrannies, the despotism of priestcraft. They live in more solemn fear of the frowns of a bigot who has been dead and rotten above a thousand years, than of the living despot whose frown would cost them their lives…The ignorance, superstitious tradition and civil and religious tyranny, which depress the human mind here, exclude improvement of every kind…"

Alexis de Tocqueville:

"I studied the Kuran a great deal ... I came away from that study with the conviction that by and large there have been few religions in the world as deadly to men as that of Muhammed. As far as I can see, it is the principal cause of the decadence so visible today in the Muslim world, and, though less absurd than the polytheism of old, its social and political tendencies are in my opinion infinitely more to be feared, and I therefore regard it as a form of decadence rather than a form of progress in relation to paganism itself."

G.K. Chesterton:

There is in Islam a paradox which is perhaps a permanent menace. The great creed born in the desert creates a kind of ecstasy of the very emptiness of its own land, and even, one may say, out of the emptiness of its own theology. . . . A void is made in the heart of Islam which has to be filled up again and again by a mere repetition of the revolution that founded it. There are no sacraments; the only thing that can happen is a sort of apocalypse, as unique as the end of the world; so the apocalypse can only be repeated and the world end again and again. There are no priests; and yet this equality can only breed a multitude if lawless prophets almost as numerous as priests. The very dogma that there is only one Mahomet produces an endless procession of Mahomets.

Winston Churchill 14 June 1921:

‘The Wahabis profess a life of exceeding austerity, and what they practice themselves they rigorously enforce on others. They hold it as an article of duty, as well as of faith, to kill all who do not share their opinions and to make slaves of their wives and children. Women have been put to death in Wahabi villages for simply appearing in the streets. It is a penal offense to wear a silk garment. Men have been killed for smoking a cigarette, and as for alcohol, the most energetic supporter of the temperance cause in this country falls far behind them. Austere, intolerant, well armed, and bloodthirsty, in their own regions the Wahabis are a distinct factor which must be taken into account, and they have been, and still are, very dangerous to the holy cities of Mecca and Medina, and to the whole institution of the pilgrimage, in which our Indian fellow-subjects are so deeply concerned….The Emir Bin Saud has shown himself capable of leading and, within considerable limits, of controlling these formidable sectaries.'

Winston Churchill:

"How dreadful are the curses which Mohammedanism lays on its votaries! Besides the fanatical frenzy, which is as dangerous in a man as hydrophobia in a dog, there is this fearful fatalistic apathy. The effects are apparent in many countries. Improvident habits, slovenly systems of agriculture, sluggish methods of commerce, and insecurity of property exist wherever the followers of the Prophet rule or live. A degraded sensualism deprives this life of its grace and refinement; the next of its dignity and sanctity. The fact that in Mohammedan law every woman must belong to some man as his absolute property must delay the final extinction of slavery until the faith of Islam has ceased to be a great power among men. Individual Moslems may show splendid qualities. Thousands become the brave and loyal soldiers of the Queen; all know how to die; but the influence of the religion paralyses the social development of those who follow it. No stronger retrograde force exists in the world. Far from being moribund, Mohammedanism is a militant and proselytizing faith. It has already spread throughout Central Africa, raising fearless warriors at every step; and were it not that Christianity is sheltered in the strong arms of science the civilisation of modern Europe might fall, as fell the civilisation of ancient Rome."

And how about this quote from Ayatollah Khomeini from 1942:

“Islam makes it incumbent on all adult males, provided they are not disabled and incapacitated, to prepare themselves for the conquest of [other] countries so that the writ of Islam is obeyed in every country in the world. But those who study Islamic Holy War will understand why Islam wants to conquer the whole world…. Those who know nothing of Islam pretend that Islam counsels against war. Those [who say this] are witless. Islam says Kill all the unbelievers just as they would kill you all! Does this mean that Muslims should sit back until they are devoured by [the unbelievers] Islam says Kill them [the non-Muslims], put them to the sword and scatter [their armies]. Does this mean sitting back until [non-Muslims] overcome us Islam says Kill in the service of Allah those who may want to kill you! Does this mean that we should surrender to the enemy Islam says Whatever good there is exists thanks to the sword and in the shadow of the sword! People cannot be made obedient except with the sword! The sword is the key to Paradise, which can be opened only for Holy Warriors! There are hundreds of other [Koranic] verses and Hadiths [sayings of the Prophet] urging Muslims to value war and to fight. Does all that mean that Islam is a religion that prevents men from waging war I spit upon those foolish souls who make such a claim.” - Ayatollah Khomeini

In defense of the UK, Winston Churchill 1941:

You cannot tell from appearances how things will go. Sometimes imagination makes things out far worse than they are; yet without imagination not much can be done. Those people who are imaginative see many more dangers than perhaps exist; certainly many more than will happen; but then they must also pray to be given that extra courage to carry this far-reaching imagination. But for everyone, surely, what we have gone through in this period - I am addressing myself to the School - surely from this period of ten months this is the lesson: never give in, never give in, never, never, never, never-in nothing, great or small, large or petty - never give in except to convictions of honour and good sense. Never yield to force; never yield to the apparently overwhelming might of the enemy. We stood all alone a year ago, and to many countries it seemed that our account was closed, we were finished. All this tradition of ours, our songs, our School history, this part of the history of this country, were gone and finished and liquidated
