Oseas I would like to address the little horn in your post.
Daniel 7-8 the little horn/4th beast
The seven heads are that of the Babylonian Empire: (Iraq), Medo - Persian Empire: (Iran), Grecian Empire: (Greece, Turkey, Syria, Egypt), Roman Empire. The ten horns represent the nations the Roman Empire scattered to when the deadly wound was put upon them, Daniel 7:23-25.
These ten nations were the Anglo-Saxons (English), the Franks (French), Suevi (Portuguese), Visigoths (Spanish), Burgundians (Swiss), Alemanni (Germans), Lombards (Italians), Ostrogoths, Heruli, and the Vandals in northern Africa. The last three being Ostrogoths, Heruli, and the Vandals had already been destroyed by the Roman Empire before their deadly wound came in 1798.
Seven remaining nations that still exist today:
Babylonian Empire:
(Iraq) The lion represents the winged lions that guarded the royal places of Babylon.
Medo – Persian Empire:
(Iran) The ribs of the bear are part of the consuming greed that devours the first empire.
Grecian Empire:
(Greece, Turkey, Syria, Egypt) Four wings of the leopard described the swiftness of this empire that ran from 334-331BC. It wrestled world dominion from Medo-Persia. After the death of Alexander the Great the kingdom was divided into four minor kingdoms that continued as prominent factors in world politics until the Roman Empire gathered it back as one kingdom.
Roman Empire: (little horn, Daniel 8:9-14, 23-27)
Iron represents the stronghold this nation had. Daniel chapter 2 mentions the iron element of this empire that it to will be divided and broken as God will set up a kingdom that will never be destroyed.
Rev 12:3 the other sign John saw was a great red dragon meaning Satan. Remember, this is a vision and a sign as Satan has not yet been cast out of heaven until the beginning of the 3 1/2 year tribulation. The description of the dragon being great and red depicts its nature and character as being fierce and murderous, John 8:44. This red dragon is depicted as having seven heads, ten horns, and seven crowns upon his heads. This is also confirmed in Rev 17 as mystery Babylon is described. The seven heads and ten horns refer to the original ten kingdoms of which three were subdued by the little horn of Daniel 7:8. The last kingdom which stands greater than all the others is that of a revived Roman Empire that takes control over all the ten nations who then implements a deceiving peace treaty with the Muslims in which the Dome of the Rock will be given over to the son of perdition as he reigns from the very Temple mount of God. This is the abomination Jesus spoke of in Matthew 24:15, 16 that we are to flee from when we see the son of perdition take his seat in Jerusalem for 3 1/2 years.
Rev 13 the beast rises up out of the sea as the sea here is symbolic of people and nations as in a sea of humanity, Daniel Chapter 7:1-8; Revelation 17:15. This beast is a Luciferian system comprised of economic, political, militant, environmental and a false religious system. This beast system that Satan works through gives its power to the beast out of the earth as the beast out of the earth appears as the Lamb of God, but is a false Christ being the son of perdition, 2 Thessalonians 2:3-12 with two horns. The two horns represent the Old Roman Empire that received its deadly wound back in 1798 by General Berthier who made his entrance into Rome and abolished the Roman government and established a secular one. That caused them to scatter into the other ten nations (ten horns). The wound was healed in 1929 by Mussolini.
