Dan 7:23-24 "Thus he said: 'The fourth beast shall be a fourth kingdom on earth, which shall be different from all other kingdoms, and shall devour the whole earth, trample it and break it in pieces. The ten horns are ten kings who shall arise from this kingdom..."
The Northern Alliance of Iran (4th Beast) is also the little horn that is part of the former Grecian Empire. He will conquer Israel and many other lands.
Dan 8:8-9 Therefore the male goat grew very great; but when he became strong, the large horn was broken, and in place of it four notable ones came up toward the four winds of heaven. And out of one of them came a little horn which grew exceedingly great toward the south, toward the east, and toward the Glorious Land.
Mat 24:7 For nation will rise against nation, and kingdom against kingdom. And there will be famines, pestilences, and earthquakes in various places.
As Iran and its allies were annihilating the might of the West in World War 3, God causes great earthquakes and tsunamis, pestilences, etc. to hit all nations.
These great earthquakes with huge tsunamis killing hundreds of millions of people worldwide will temporary stop all wars. Rescue of the affected will be top priority. With such extensive destructions by the greatest earthquakes and largest tsunamis ever, the rescue will be insurmountable in every nation. Everyone will be trying to reach and rescue their loved ones, friends, etc., and no one will want to fight anymore thus ending WW3.
These great devastations will wipe out factories, food-storages, farmlands, hospitals, power, etc. causing extensive starvation. The wounded, sick and starving along with plagues, diseases, etc. will bring all mankind onto their knees.
During this period God will cleanse His church by killing the depraved, covetous and heretic pastors and Christian leaders to prepare the bride of the Lamb
This will also be the period that godly Christians armed with the vision of the greatest harvest of souls, and the mission to feed, care, comfort and heal all the affected with God's gifts and empowering.
Rev 17:10-12 "The ten horns which you saw are ten kings who have received no kingdom as yet, but they receive authority for one hour as kings with the beast."
After World War 3, the victorious but decimated (by the natural calamities) Northern Alliance (legs of iron) will form the One World Order to replace the ineffective and abominable UN.
Dan 2:32-33 "This image's head was of fine gold, its chest and arms of silver, its belly and thighs of bronze, its legs of iron, its feet partly of iron and partly of clay."
Dan 2:41-42 Whereas you saw the feet and toes, partly of potter's clay and partly of iron, the kingdom shall be divided; yet the strength of the iron shall be in it, just as you saw the iron mixed with ceramic clay. And as the toes of the feet were partly of iron and partly of clay, so the kingdom shall be partly strong and partly fragile.
All the first four beasts are of metal (gold, silver, bronze and iron) representing political and military powers, but the new government that comes out of this 4th Beast (iron) will be different. This new government (One World Order) being the feet and toes of the image were made of iron and clay. Since iron (metal) represents military or political power, then clay will likely represent the religious powers.
The new 'One World Order' will have 10 representatives (kings) to rule the whole world.
