‘Obviously the source of this global phenomenon is demonic.’
and since God created all, including demons, then the source is...?
Demonic, not God. God created angels and gave them free will. Their free will is more limited in many ways then ours, but the fallen angels have considerable latitude in the affairs of the world and have for all of the ages. God granted them knowledge of good and evil, and their choice to do evil is not from God, but from their own.
