Second Seal: Islam rides a Red Horse
3 When He opened the second seal, I heard the second living creature saying, "Come *and see."
4 Another horse, fiery red, went out. And it was granted to the one who sat on it to take peace from the earth, and that people should kill one another; and there was given to him a great sword.
==Second Seal: Islam rides a Red Horse
I wouldn't assume that Islam itself makes up the rider on the Red Horse. Don't forget about Russia (red), Red China (red), and the EU of the future (red)...in short the Eurasian Alliance.
