...or this:
VIII/65: "O Prophet! Exhort the believers to fight. If there be of you twenty steadfast they shall overcome two hundred, and if there be of you a hundred stedfast they shall overcome a thousand of those who disbelieve, because they (the disbelievers) are a folk without intelligence."
...this...
VIII/12: "When thy Lord inspired the angels, (saying:) I am with you. So make those who believe stand firm. I will throw fear into the hearts of those who disbelieve. Then maim them in every limb and smite of them each finger."
I realize different versions probably compete, with rough edges in some removed (or flat out lying) for Western consumption. I'd like a link to the version that has the translation for your quotes, as it sounds closer to reality.
Ibn Tayymia in the middle ages tried to extend the meaning to include essentially anyone who disagreed with him, including muslims that revered local saints and the like. This was an innovation and denounced as heresy in his own time; he died in prison. The Wahhabis follow many of his teachings.
The aggressive application of statements in the Koran about "unbelievers" to "peoples of the book" and non-islamicist muslims is denounced by traditional sunnis, as the original article made clear. This is indeed one of the key fronts in the fight within islam. It is enough to transform the historical nuance of the tradition into a totalitarian ideology that persecutes anyone who does not accept the ideology wholesale.
