No one can say for sure that the pale (green) horse in the news video from Cairo is the pale (green) horse of Revelation 6:8. However, the arguments against it so far are unconvincing, such as it being a reflection or an image. Those dots on the screen are not a valid argument. I can see no natural explanation.
An argument for it is that the horse is green, just like in Revelation 6:8. With all the colors on that video, or in the rainbow, why is this horse green? There is no other green in the video from which it could be a reflection. It is important to note that green is also the color of Islam
Another argument is the times in which we live, with the death cult Islam a growing global threat. The rider on that horse is named Death, and hades follows him. That is a good description of Islam.
