Robdar,
The Koran might not consider Jews or Christians infidels, it is not very friendly towards them either:
2:61 (the cow) And humiliation and wretchedness were stamped upon them [jews] and they were visited with wrath from Allah. That was because they disbelieved in Allah's revelations and slew the prophets wrongfully. That was for their disobedience and transgression.
2: 62 Lo! Those who believe (in that which is revealed unto thee, Muhammad), and those who are Jews, and Christians, and Sabaeans - whoever believeth in Allah and the Last Day and doeth right - surely their reward is with their Lord, and there shall no fear come upon them neither shall they grieve.
2: 96 And thou wilt find them [jews] greediest of mankind for life and (greedier) than the idolaters. (Each) one of them would like to be allowed to live a thousand years. And to live (a thousand years) would be no means remove him from the doom. Allah is Seer of what they do.
And 'infidels' does not only mean Atheists either:
2: 257 Allah is the Protecting Guardian of those who believe. He bringeth them out of darkness into light. As for those who disbelieve, their patrons are false deities . They bring them out of light into darkness. Such are rightful owners of the Fire. They will abide therein.
some texts (3:85; 4:14; 4:56) do give the impression that only Muslims will be acceptable to Allah, contradicting 2:62 above:
3: 85 And whoso seeketh as religion other than the Surrender (to Allah) it will not be accepted from him, and he will be a loser in the Hereafter.
4:14 And whoso disobeyeth Allah and His messenger and transgresseth His limits, He will make him enter Fire, where he will dwell for ever; his will be a shameful doom.
4:56 Lo! Those who disbelieve Our revelations, We shall expose them to the Fire. As often as their skins are consumed We shall exchange them for fresh skins that they may taste the torment. Lo! Allah is ever Mighty, Wise.
As is rather clear the Koran is like the Bible: full of contradictions, however one thing is sure: the Muslim considers himself to be in possession of the only truth and all those that oppose this truth awaits death, either directly by Allah, or by his servants in Holy War (Jihad). Participating in waging Holy War against the infidels is not voluntary, according to the Koran but a sacred duty.
