Salaam czmead,
I have a bad feeling that WW3 is coming and have had that for a while. The global crisis is worsening and governments starts to become desperate, and countries like N. Korea act out strange.
I think something like you said is about to happen, that Satan is acting out in a desperate move, as the Truth will expand with the new God alone movement.
It is probably true that a religious group will be a culprit in the upcoming conflict, but I think traditional Islam is one part and the West with the distorted Christianity on the other. I think the war will not start on these causes, but the name of god will be misused.
If now myths about a kind of antichrist is true, I am sure God will send a holy warrior, a kind of messenger who will oppose this madness. God will protect the righteous, always.
These are feelings I have have, but I may of course be wrong.
The antichrist story is only an allegory of course, and is Satan's evil works in action. But I am sure God has not said the last word...
God bless you
