White horse - Everyone assumes these are all evil... Step away and look:
The white horseman is given a crown. And he has a bow. Who has a bow in the Tanakh? Ephraim. This is Ephraim going forth to become a 'great nation in the midst of the earth'. Everyone understands the 'death of the testator' from a Christian point of view, but who looks back at the promises to Israel? They too require the death of the testator - The blessings are inherited down the line, but who is the testator? Abraham? No...
The white horse culminates in Britain and the US... the western Republic form... those who fled from before the dragon into the wilderness.
The red horse culminates in communism.
The black horse culminates in Mohammedanism.
And the green horse presumably is the 'new world order'.
These are the end-time alignments/philosophies. And they rose to world power according to their progression.
There are only two white horsemen in Revelation, the one going forth to battle at Armageddon, Rev. 19, is the true Christ; the one going forth to battle in seal one is the false Christ, or antichrist. He goes forth on a white horse as Christ will, but he is an impostor. A counterfeit.
In ancient times, great conquerors rode white horses. A white horse was quite symbolic.
In the prophetic passages of the Bible that deal with the tribulation, the antichrist is the most conspicuous event, the central figure of the end time, this is why he, in the first seal, kicks everything off. He begins the series of events that culminate with his destruction by the TRUE Christ, also on a white horse, in Rev. 19.
I am well aware of who Ephraim is in history, and in the present, but while he became a great nation, he was stymied in becoming a good nation.
That nation lost its way a century ago.
