Was the founder of Islam a war criminal?

Though Islam is promoted by it's members and pundits to the uninitiated as simply a religion, questionable messages from group members such as number of members that follow this ideology, are in fact political statements. The discussion of religion is endless between the the West and Islam, and continually confusing to ordinary people yet it should be argued that ideologically everything religious about Islam is summed up in one thought stated around 40-50 AD many centuries before Islam was developed: You believe in one God, that's great! So do demons and they tremble. Aside from this and the pre-Islamic Arab traditions and rituals subsequently incorporated along with the personal idiosyncrasies of the founder(s) that were progressively added to help flesh out an adopted creed, it should be argued there is little religious substance within this political system to speak of. So it is necessary to ask many thoughtful questions regarding the politics of Islam, without bringing up the subject of Islam's religious aspect. For example, from a political point of view, though the founder of Islam did not engage in battles against armies but instead raids against commercial caravans and civilian populations, to say that the founder was engaged in war is true and thus the actions should be judged in a political sense using historical and modern criteria.

The religious aspect of Islam can be seen as a veneer and thus instead be regarded as a political system. It is and always was a political movement so Americans need to ask questions like, do we believe political groups such as Islam should be free and unrestricted within the USA in their implied and stated political goal of dominating all other non-members individuals and groups? If you doubt Islam's religious aspect is only a thin covering for a political/power system, consider the following statistical study here. Only 2.6% of the Koran "talks about the overall good of humanity", while the majoring of Koran (61%) speaks "ills of unbelievers or calls for their violent conquest and subjugation".

Other questions might be, do Americans believe it is moral for members of political organizations such as Islam to deceive non-members if it is in the best interest to the growth of their organization and to retain such practices within their founding documents? Do Americans believe political groups such as Islam should retain and have the right to practice, display, spread or advocate violent, oppressive, hateful and bigoted articles written in their founding documents?
Again, one god, lots of rituals, adopted tenets; got it, ignored, now deal with this political movement and its messages and actions.
