The Fifth Seal predicts a great martyrdom of Christians:

{6:9} And when he had opened the fifth seal, I saw, under the altar, the souls of those who had been slain because of the Word of God and because of the testimony that they held.
{6:10} And they were crying out with a loud voice, saying: “How long, O Holy and True Lord, will you not judge and not vindicate our blood against those who dwell upon the earth?”
{6:11} And white robes were given to each of them. And they were told that they should rest for a brief time, until their fellow servants and their brothers, who were to be slain even as they were slain, would be completed.

This prediction of a great Holocaust of Christians is given in a subtle manner. But we read that the past martyrs are told of more martyrdoms — “their fellow servants and their brothers, who were to be slain even as they were slain”. This phrasing indicates that the fifth Seal is a brief time of intense martyrdom of Christians. I would compare this time to the Jewish Holocaust, but whereas 6 million Jews were killed in the Jewish Holocaust of WW2, the Christians Holocaust sees even more Christians killed between WW3 and WW4.

In my speculative eschatology, this martyrdom occurs during the occupation of Europe by the Muslim extremists. They see to force everyone to adopt their own extreme version of Islam, and those who refuse are imprisoned, tortured, or murdered.

One of the reasons that the U.S. and other free nations initiate WW4 is to stop this massacre of Christians in the occupied nations of Europe.\
