Suddenly want to explain the book of Revelation, don't know right?  But we can confirm soon!

 (Revelation 9:14) Saying to the sixth angel which had the trumpet, Loose the four angels which are bound in the great river Euphrates.～These four angels should be: The leaders of Russia, Iran, North Korea and Japan!

 (Revelation 12:3) And there appeared another wonder in heaven; and behold a great red dragon, having seven heads and ten horns, and seven crowns upon his heads.～This should be the leader of China!

 (Revelation 13:1) And I stood upon the sand of the sea, and saw a beast rise up out of the sea, having seven heads and ten horns, and upon his horns ten crowns, and upon his heads the name of blasphemy.  ~Here are the leaders of the US, UK and EU!

 (Revelation 13:11) And I beheld another beast coming up out of the earth; and he had two horns like a lamb, and he spake as a dragon.～This should be the Indian leader!

 Simple explanation is over!  We'll just wait to see if the book of Revelation is moving forward...the plague kills 1/4...the fulfillment means that the book of Revelation is already running!
