What does the red horse of Revelation 6 represent?

Les explains that when he taught the red horse of Revelation 6, he would ask his classes about it and say he thinks it is the northern invasion of Ezekiel 38 and 39. He is careful to call this his own speculation and says he cannot prove it from Scripture. He illustrates the idea by asking what a Russian general or chief of staff would do before invading the Middle East and Israel. He reasons that Russia would first unload everything on North America, because America is the only power that could counteract the invasion. So he thinks that just before the great invasion of Israel, probably within the first year of the tribulation, the Russians will unload everything on America and America will be off the scene, since he cannot find America in prophecy. Prophecy, as he describes it, deals only with Western Europe, Russia, the Orient, and Africa. He again calls this a conjecture.
