Yes, you are correct. The article does state that he is a Christian. Maybe this will, in fact, ultimately boil down to a war between Islam and the rest of the world.
There is no "maybe" about it. This is a war between true good and true evil or God & Satan, or Judeo-Christianity and Islam.
Islam is the religion of Satan as plain as the Apostle John could write it in his letter of 1 John 2. The spirit of anti-Christ now come into the world: "Who is a liar but he who denies that Jesus is the Christ? He is antichrist who denies the Father and the Son. Whoever denies the Son does not have the Father either; he who acknowledges the Son has the Father also.
This war will last until Jesus returns...unless we eliminate every last one of them. Appeasement, ceasefire, pull-back only gives them time to regroup and re-arm. No "deals" can be made with the the devil Satan...just as no deals can be made with rabid dogs.
Consider what One-eyed cleric Abu Hamza al Masri said, "Jihad, in general, is striving for [the] sake of God to establish his law…on earth, and the backbone of his law is fighting. So every fighting cause of God is Jihad. What are [the] consequences for infidels? If you live in my property, and you don't pay me my rent, then you get out and Jihad is to get you out. This is the property of God. You don't worship him, you get out and how [do] you get out? You get killed."
So, think this "maybe will be against Islam and the rest of the world?"
Well, in my belief, it will be Christian America (as long as we are a Christian nation) along with Israel against Islam. As for Europe, they have gone over to the "dark side" and are siding with our enemies (except for perhaps Britain...for now) .
