For those interested, this is a hoax originally dating to 1896, and has a very interesting history as it's been handed down, added to, and translated from English to French to Spanish back to English again, over the last hundred and twenty-seven years.

In 1896, a publication appeared in Paris called Le Diable au XIXe Siècle (English: The Devil in the 19th Century), an attack on Freemasonry by an anti-Masonic and anti-Catholic writer named Leo Taxil a.k.a. Dr. Bataille. In it, among other things, was claimed to be the full transcription of a letter from August 15th, 1871, from General Albert Pike to Joseph Mazzini, both prominent (and real) Masons who lived at that time, outlining the plan for Masonic domination of the world via the destruction of the Catholic Church. Translated directly from French, it reads:

Therefore, when the autocratic Empire of Russia will become the citadel of papist adonaism, we shall unleash the revolutionary nihilists and atheists, and provoke a formidable social cataclysm, which will demonstrate clearly to the nations, in all its horror, the effect of absolute unbelief, mother of savagery and of the bloodiest disorder. Then everywhere, the citizens, obliged to defend themselves against the mad minority of revolutionaries, will exterminate these destroyers of civilization; and the countless disillusioned adonaites, whose deist soul have up until that time remained without a compass, thirsting for an ideal, but not knowing which God is worthy of tribute, will receive the True Light, by the universal manifestation of the pure Luciferian doctrine, at last made public, an event that will arise from a reactionary movement following the destruction of atheism and adonaism, together at the same time vanquished and exterminated.

We know this to be a hoax, largely because Taxil himself admitted to it being a hoax some years later, along with dozens of other anti-Masonic and anti-Catholic pieces he'd written. But, what's noteworthy is that it has nothing about a "Third World War", or about Islam, or Zionism, all of which would have been astonishing predictions for 1871. The first three sentences of the quote OP provided are not present in the original, nor anything like it. To find out where the rest came from, we have to trace it down.

This letter was first translated into English in 1920, in the book The Cause of World Unrest, and the paragraph above was included verbatim. Cardinal Caro y Rodriguez of Santiago translated it into Spanish in his 1925 book The Mystery of Freemasonry Revealed; the book was later translated back into English in the 1950s. So far - aside from the fact that it was made up to begin with - so good. But then, William Guy Carr, in his 1956 book Pawns in the Game, paraphrased it by saying that the original letter was about the first, second, and third world wars, saying:

The first world war was to be fought so as to enable the Illuminati to overthrow the powers of the Tzars in Russia and turn that country into the stronghold of Atheistic-Communism. The differences stirred up by agentur of the Illuminati between the British and German Empires were to be used to foment this war. After the war ended, Communism was to be built up and used to destroy other governments and weaken religions.

World War Two, was to be fomented by using the differences between Fascists and Political Zionists. This war was to be fought so that Naziism would be destroyed and the power of Political Zionism increased so that the sovereign state of Israel could be established in Palestine. During world war two International Communism was to be built up until it equalled in strength that of united Christendom. At this point it was to be contained and kept in check until required for the final social cataclysm. Can any informed person deny Roosevelt and Churchill did not put this policy into effect?

World War Three is to be fomented by using the differences the agentur of the Illuminati stir up between Political Zionists and the leaders of the Moslem world. The war is to be directed in such a manner that Islam (the Arab World including Mohammedanism) and Political Zionism (including the State of Israel) will destroy themselves while at the same time the remaining nations, once more divided against each other on this issue, will be forced to fight themselves into a state of complete exhaustion physically, mentally, spiritually and economically. Can any unbiased and reasoning person deny that the intrigue now going on in the Near, Middle, and Far East isn’t designed to accomplish this devilish purpose?

The bit about World War Three was commentary about the letter by Carr - he included the rest of the quote a couple pages later - and was not at all accurate to what the letter actually said, given that the letter was all about how to destroy the Catholic Church through an elaborate plan involving kicking the Pope out of Vatican City (disregarding, of course, the fact that the 'letter' was made up to begin with). His source was the English translation of Cardinal Rodriguez's The Mystery of Freemasonry Revealed, which also didn't have anything about World War Three, so he just made those parts up.

And then it lay dormant for another fifty years, re-emerging on the website http://threeworldwars.com/ in 2003 by Michael Haput, shortly after the Iraq war started. And it was Michael Haput who joined Carr's 'paraphrasing' with the original letter to create the quote OP provided, to make it seem as though a Freemason in 1871 had accurately predicted the first two world wars perfectly. You can see Michael Haput's original article on Albert Pike here, including the 'predictions' for all three world wars. You'll also notice that the current version of that page does not have any of those quotes on it.

You other commenters might scoff at OP's flippant responses, but with a quote whose origin is this disingenous, can you blame him for not wanting to answer?
