Roger Gardner, writing at Radar Site about a vital lesson of history, propounds the following question.
And what, one might legitimately ask, was the Muslim grievance that caused those (seemingly never-ending) eighteenth century acts of piracy on the Barbary Coast? Were they in any way similar to the Muslim complaint that precipitated that infamous and deadly attack on the Munich Olympics?
Jihad: Doctrine DrivenIslam's Jihad is not grievance driven, it is doctrine driven. The following quote comes from Wikipedia.
In 1786 Jefferson and John Adams went to negotiate with Tripoli's envoy to London, Ambassador Sidi Haji Abdrahaman or (Sidi Haji Abdul Rahman Adja). They asked him by what right he extorted money and took slaves. Jefferson reported to Secretary of State John Jay, and to the Congress:Jefferson and Adams were dealing with Islamic supremacism & triumphalism.. Islamic law is based upon the Qur'an & hadith. 4:74, Volume 4, Book 53, Number 386 contains a vitally important quote which matches the Ambassador's arrogant answer.
The ambassador answered us that [the right] was founded on the Laws of the Prophet (Mohammed), that it was written in their Koran, that all nations who should not have answered their authority were sinners, that it was their right and duty to make war upon them wherever they could be found, and to make slaves of all they could take as prisoners, and that every Mussulman (or Muslim) who should be slain in battle was sure to go to heaven. 
Our Prophet, the Messenger of our Lord, has ordered us to fight you till you worship Allah Alone or give Jizya (i.e. tribute); and our Prophet has informed us that our Lord says:-- "Whoever amongst us is killed (i.e. martyred), shall go to Paradise to lead such a luxurious life as he has never seen, and whoever amongst us remain alive, shall become your master."The order mentioned in that hadith is found in Surah At-Taubah 29, in the form of an outcome oriented fight until loop.
Another hadith reveals how Moe interpreted that command.
9:29. Fight against those who (1) believe not in Allâh, (2) nor in the Last Day, (3) nor forbid that which has been forbidden by Allâh and His Messenger (4) and those who acknowledge not the religion of truth (i.e. Islâm) among the people of the Scripture (Jews and Christians), until they pay the Jizyah with willing submission, and feel themselves subdued.
Bukhari Volume 1, Book 8, Number 387:Our lives and property are not sacred to Muslims, in essence fair prey, until we become Muslims. Moe declared open season on us. Jihad is not about any act or omission on our part, it is about what "Allah said" and Moe did. To put an end to Jihad, we must put an end to Islam. Nobody wants to recognize that fatal fact. My mission is to rub your nose in it until you recognize it and rise up demanding that our government take effective action.
Narrated Anas bin Malik:
Allah's Apostle said, "I have been ordered to fight the people till they say: 'None has the right to be worshipped but Allah.' And if they say so, pray like our prayers, face our Qibla and slaughter as we slaughter, then their blood and property will be sacred to us and we will not interfere with them except legally and their reckoning will be with Allah." Narrated Maimun ibn Siyah that he asked Anas bin Malik, "O Abu Hamza! What makes the life and property of a person sacred?" He replied, "Whoever says, 'None has the right to be worshipped but Allah', faces our Qibla during the prayers, prays like us and eats our slaughtered animal, then he is a Muslim, and has got the same rights and obligations as other Muslims have."
The promise of Paradise is alluded to in Surah An-Nisa' 74.
4:74. Let those (believers) who sell the life of this world for the Hereafter fight in the Cause of Allâh, and whoso fights in the Cause of Allâh, and is killed or gets victory, We shall bestow on him a great reward.
Islamic law confirms Allah's abominable command. It tells us that the caliph makes war on us; that it is a communal obligation binding upon Muslims, in every year. I quote from Umdat as-Salik. Book O, Chapter 9.
O9.1: The Obligatory Character of Jihad
Jihad is a communal obligation (def: c3.2). When enough people perform it to successfully accomplish it, it is no longer obligatory upon others (O: the evidence for which is the Prophet's saying (Allah bless him and give him peace),
"He who provides the equipment for a soldier in jihad has himself performed jihad,"
and Allah Most High having said:
"Those of the believers who are unhurt but sit behind are not equal to those who fight in Allah's path with their property and lives. Allah has preferred those who fight with their property and lives a whole degree above those who sit behind. And to each, Allah has promised great good" (Koran 4:95).
If none of those concerned perform jihad, and it does not happen at all, then everyone who is aware that it is obligatory is guilty of sin, if there was a possibility of having performed it. In the time of the Prophet (Allah bless him and give him peace) jihad was a communal obligation after his emigration (hijra) to Medina. As for subsequent times, there are two possible states in respect to non-Muslims.
The first is when they are in their own countries, in which case jihad (def: o9.8) is a communal obligation, and this is what our author is speaking of when he says, "Jihad is a communal obligation," meaning upon the Muslims each year.
The second state is when non-Muslims invade a Muslim country or near to one, in which case jihad is personally obligatory (def: c3.2) upon the inhabitants of that country, who must repel the non-Muslims with whatever they can).
O9.8: The Objectives of Jihad
The caliph (o25) makes war upon Jews, Christians, and Zoroastrians (N: provided he has first invited them to enter Islam in faith and practice, and if they will not, then invited them to enter the social order of Islam by paying the non-Muslim poll tax (jizya, def: o11.4) -which is the significance of their paying it, not the money itself-while remaining in their ancestral religions) (O: and the war continues) until they become Muslim or else pay the non-Muslim poll tax (O: in accordance with the word of Allah Most High,
"Fight those who do not believe in Allah and the Last Day and who forbid not what Allah and His messenger have forbidden-who do not practice the religion of truth, being of those who have been given the Book-until they pay the poll tax out of hand and are humbled" (Koran 9.29),...
