Here are some excerpts from Qutb's Milestones.  One thing to really key in on is that this is linked on various mainstream Islamic websites.  This is by no means a soft document, read it and get a better idea of what radical Isam is all about.  I consider it essential reading to have any clear sense of what we are facing...

From Milestones:

"Another reason may have been that the Muslims were few in number and they lived only in Mecca, as the message of Islam had not reached other parts of Arabia or had reached only as hearsay. Other tribes considered it as a domestic quarrel of the Quraish; they were watching for the outcome of this struggle. Under these circumstances, if fighting had been allowed, this limited warfare would have resulted in the complete annihilation of the Muslims; even if they had killed a great number of their opponents, they would still have been completely annihilated. Idolatry would have continued and the dawn of the Islamic system would never have arrived and would never have reached its zenith, while Islam is revealed to be a practical way of life for all mankind".

In the early Medinite period fighting was also prohibited. The reason for this was that the Prophet - peace be on him- had signed a pact with the Jews of Medina and with the unbelieving Arabs in and around Medina, an action which was necessary at this stage.

First, there was an open opportunity for preaching and persuasion. There was no political power to circumscribe this freedom; the whole population accepted the new Muslim state and agreed upon the leadership of the Prophet-peace be on him-in all political maners. In the pact it was agreed by all parties that no one would make a treaty of peace or declare war or establish relations with any outsider without the express permission of the Prophet - peace be on him. Thus, the real power in Medina was in the hands of Muslim leadership. The doors were also open for preaching Islam and there was freedom of belief.

Secondly, at this stage the Prophet-peace be on him - wanted to conserve all his efforts to combat the Quraish, whose relentless opposition was a great obstacle in spreading Islam to other tribes which were waiting to see the final outcome of the struggle between the two groups of the Quraish. That is why the Prophet - peace be on him - hastened to send scouting parties in various directions. The first such party was commanded by Hamza bin Abdul Muttalib, and it went out during the month of Ramadan, only six months after the Immigration.

After this, there were other scouting parties, one during the ninth month after Hijra, the next in the thirteenth month the third sixteen months after Hijra, and in the seventeenth month he sent a party under the leadership of Abdullah bin Jahash. This party encountered some resistance and some blood was shed. This occurred during the month of Rajab, which was considered a sacred month. The following verse of Chapter Baqara refers to it:
"They ask you about fighting in the sacred months. Say: Fighting in them is a great sin, but to prevent people from the way of God, and to reject God, and to stop people from visiting the Sacred Mosque, and to expel people from their homes are a much greater sin, and oppression is worse than killing." (2:217)

During Ramadan of the same year, the Battle of Badr took place, and in Chapter Anfal this battle was reviewed.

If this stage of the Islamic movement is viewed in proper perspective, then there is no room to say that the basic aim of the Islamic movement was 'defensive' in the narrow sense which some people ascribe to it today, defeated by the attacks of the treacherous orientalists!
