BEAST VS. DRAGON ?
Over 15+ years ago this student of Bible Prophecy came to the conclusion based on the Book of Revelation that the TWO largest / most dominating military forces during the Battle of Armageddon will be those of the Kingdom of the Beast and those of the KIng's of the East very simply because the Book of Revelation really only mentions those two by name, sure there will be other much smaller armies in Armageddon but these TWO will be the main one's. We also know 'biblically speaking' that by the time of the 'Abomination of Desolation' both the U.S. Armed Forces as well as the Russian Armed Forces will have suffered major setbacks and losses because of the wars to be played out in Ezekiel 38 and others.
By the time the 'Great Tribulation' period begins ( final 3 and a half years*) the KIng of the North : Russia will have already suffered massive military losses during the Ezekiel 38 war and also the King of the South : Islamic countries; thus at the height of the Battle of Armageddon the TWO biggest military powers left standing will be those of the 'Kingdom of the Beast' and the 'King's of the East' !!!
