Al Quada and Islam are synomymous. Their own leaders admit such.

"And Romia is the city we name Rome, the capital of Italy. The city of Herqel [Constantinople] was conquered in 1453 by the young Ottoman, aged 23, Muhammad Ibn Mourad, known by his nickname Muhammad the Conqueror. Nowadays, the conquest of the other city Romia [Rome] remains unfulfilled. Namely, Islam will return once more to Europe as a conqueror and as a victorious power after it was expelled twice from the continent....I assume that next time the conquest [of Europe] will not be achieved by the sword [i.e., war] but by preaching (daawa) and spreading the ideology [of Islam]....The conquest of Romia [Rome] and the expansion of Islam will reach all the areas where the sun shines and the moon appears [i.e., the entire world]....That will be the result of a planted seed and the beginning of the righteous Caliphate's return....[The Islamic Caliphate] deserves to lead the nation to the plains of victory.
AND from jihadwatch.org
Many passages of the Qur'an and sayings of the Prophet Muhammad are used by radical Muslims today to justify their actions and gain new recruits. No major Muslim group has ever repudiated the doctrines of armed jihad. The theology of jihad, which denies unbelievers equality of human rights and dignity, is available today for anyone with the will and means to bring it to life.
And you must have heard what OBL has said about what he want to do to the West...what mohammedans have been doing since their inception.
Well there you go then - you don't have the first clue as to what Al Qaeda is. You might want to fix that before attempting to discuss the subject any further, m'kay?
