Following this through and giving a little more detail of the emergence of this 7th head - the Anglo-American world power...
Great Britain emerged as the small horn of Daniel 7:24 in the 1700's - defeating the Dutch, the French and the Spanish, humiliating 3 Kings or horns in fulfillment of Daniel 7:24: -
Daniel 7:24 And as for the ten horns, out of that kingdom there are ten kings that will rise up; and still another one will rise up after them, and he himself will be different from the first ones, and three kings he will humiliate.
Part of the British Empire broke away and declared independence from the British Empire in 1776
WW1 broke out on the 28th July 1914 when Austria-Hungary declared war on Serbia.
Great Britain officially entered the ring on August 4th and declared war on Germany.
Three and a half years or 42 months into the war we find that Great Britain is suffering great losses, they are almost at the point of losing the war.
This was in fulfilment of Revelation 13:3: -
Revelation 13:3 One of the heads of the beast seemed to have had a fatal wound
, but the fatal wound had been healed. The whole world was filled with wonder and followed the beast.
Although being fatally wounded, it was also foretold that it would be healed, it would recover.
How did this healing and recovery come about?
The United States declared war on Germany on April 6, 1917, more than two and a half years after World War I started.
To a large extent, the backup from the United States helped turn the war around.
This total turn around by back up from the west was also foretold in Daniel chapter 11: -
(Daniel 11:29, 30) “At the time appointed he will go back, and he will actually come against the south; but it will not prove to be at the last the same as at the first. And there will certainly come against him the ships of Kitʹtim, and he will have to become dejected…
Notice how other translations render this term, ships of Kit’tim: -
New International Version
Ships of the western coastlands
will oppose him, and he will lose heart. Then he will turn back and vent his fury against the holy covenant. He will return and show favor to those who forsake the holy covenant.
New Living Translation
For warships from western coastlands
will scare him off, and he will withdraw and return home. But he will vent his anger against the people of the holy covenant and reward those who forsake the covenant.
History testifies that the United States became this foretold backup from the west.
After WW1 finished, Britain and American emerged ‘together’
This development is also seen in Revelation 13: -
(Revelation 13:11, 12) And I saw another wild beast ascending out of the earth, and it had two horns like a lamb, but it began speaking as a dragon. And it exercises all the authority of the first wild beast in its sight. And it makes the earth and those who dwell in it worship the first wild beast, whose death-stroke got healed.
After WW1 the British monarchy was pushed further into the background and a new form of leadership arose, power was transferred to that of prime ministers.
These rule in the sight of the monarchy and exercise all authority before it.
What was the plan of action after WW1, what other developments does Revelation 13 predict?
(Revelation 13:14) And it misleads those who dwell on the earth, because of the signs that were granted it to perform in the sight of the wild beast, while it tells those who dwell on the earth to make an image to the wild beast that had the sword-stroke and yet revived.
After the War ended, Britain and America fabricated a new entity, the League of Nations. Its primary goals, as stated in its Covenant, included preventing wars through collective security and disarmament and settling international disputes through negotiation and arbitration.
The American President, Woodrow Wilson, put forth great efforts to establish and promote the League of Nations, for which he was awarded the Nobel Peace Prize in October 1919.
However, the United States never joined. Senate Republicans led by Henry Cabot Lodge wanted a League with the reservation that only Congress could take the U.S. into war. Lodge gained a majority of Senators. Wilson refused to allow a compromise and the needed 2/3 majority was lacking.
Did this League of Nations prevent wars and prove to be a place where international disputes were solved through negotiation?
Well, not many years later WW2 erupted, the League of Nations had failed.
Note what is said next: -
(Revelation 13:15) And there was granted it to give breath to the image of the wild beast, so that the image of the wild beast should both speak and cause to be killed all those who would not in any way worship the image of the wild beast.
After WW2, Britain and American again emerged as victors. The same idea of the League of Nations was proposed, but this time the United States would join and support it, in effect giving breath or life to the idea, it was reborn as the United Nations.
This setup is further alluded to in Revelation 17: -
(Revelation 17:11) And the wild beast that was but is not, it is also an eighth king,
but it springs from the seven,
and it goes off into destruction.
The United Nations today uses sanctions to restrict the buying or selling of any nation that does not play ball and accept its leadership and authority.
This tactic of the United Nations was also clearly foretold in the following verses: -
(Revelation 13:16, 17) And it puts under compulsion all persons, the small and the great, and the rich and the poor, and the free and the slaves, that they should give these a mark in their right hand or upon their forehead, and that nobody might be able to buy or sell except a person having the mark, the name of the wild beast or the number of its name.
Finally in Revelation 13 we are reminded that this is an expression of ‘imperfect human’ rulership.
It is not God's promised Kingdom nor is its rulership authorized by Him.
It is a counterfeit attempt of misleading people into trusting, not in Jehovah and His promises, but in ourselves.
(Revelation 13:18) Here is where wisdom comes in: Let the one that has intelligence calculate the number of the wild beast, for it is a man’s number; and its number is six hundred and sixty-six.
(Psalm 146:3) Do not put YOUR trust in nobles, Nor in the son of earthling man, to whom no salvation belongs.
(Ecclesiastes 8:9) All this I have seen, and there was an applying of my heart to every work that has been done under the sun, [during] the time that man has dominated man to his injury.
So in conclusion, the 7th head started to emerge in the 1700's from the ashes of the Roman empire, it received a sword stroke during WW1 which almost killed it, but it recovered with the help of the USA and is now fully active on the world scene as the Anglo-American world power.
Revelation 17:10...when he does come, he must remain for only a little while.
Does it hold water?
We shall see...
Jeremiah 2:13 “My people have committed two sins: They have forsaken me, the spring of living water, and have dug their own cisterns, broken cisterns that cannot hold water.
Revelation 10:7 But in the days when the seventh angel is about to sound his trumpet, the mystery of God will be accomplished, just as he announced to his servants the prophets.”
