My own studies on the matter are that, on that GREAT DAY when the U.S. bombs Iran, then the final battle of Armageddon begins, where the Armies of the world gather for battle on the border of Lebanon/Israel. The U.S. forces will invade into Israels territory and head to Jerusalem because of something dramatic that has happened on the Temple Mount! The U.S. President who will be heavily influenced by the dark and mysterious group of the Knights Templars will seek to seize the temple mount area to supposedly protect it.

Isaiah 10:28-32, The U.S. forces will stop outside the gates of Jerusalem and will shake their fist in indignation at the temple mount of Zion. My understanding is that the Muslim mosques on the mount will be destroyed shortly by Mossad or disgruntled Israeli settlers or even perhaps by a natural collapse because of all the illegal construction that has been going on there. This will lead to immediate war with all the Arabs. It was always hinted that when a united government party was set up in Israel, that shortly after, this united government would seek to set-up a war with their neighbours. So they could increase their territory, instead of having to give land back to the Palestinians, this united war government has been finalised in the last week.
The tie-in for both this Armageddon Battle´Day of The Lord´ and the return of Planet-X affecting the earth is very interesting. As it notes in the old testament book of Joel, as this invasion into Israels territory occurs by the U.S. forces(not Russian as always espoused by U.S. preachers) Joel 2:10-11, the earth and heavens quaking & trembling, the sun and moon growing dark along with the stars. This is also foretold by Jesus himself in Matthew 24:27-31, Mark 13:24-27, Luke 21:20-28, The time when Jerusalem is surrounded by armies, signs in the sun, moon, stars, just like what is predicted to happen when Planet-X greatly effects the whole world shortly.
But of course the great hope, when the armies are fighting in Israel and the whole world is effected by Planet-X bringing about the darkness in the Middle Easts part of the world, then the mighty earthquake of God occurs when he shakes his whole creation, Joel 2:10,3:16, Isaiah 24:19-23, Isaiah 2:19-21, the Almighty reveals himself very briefly, about 1 minutes duration, his light will suddenly appear all over the earth, then no matter where any of his creation is, both alive and dead, they will see him before their eyes, as shown in Luke:21 27, Matthew 24:30, The Almighty will appear before everyones eyes just the way John saw him in at the beginning of the book of Revelation Chapter 1, as shown in Revelation 1:7-8,´behold, He is coming with clouds, and every eye will see Him, And all the tribes of the earth will mourn because of Him, Even so, Amen.´´"I am the Alpha and the Omega, the beginning and the End," says the Lord, "who is and who was and who is to come, the Almighty."
At the end of this 1 minute, the Almighty God(this is the Creator Father we will all see, not Yoshua Jesus Christ) will raise up his voice, his voice is also the trumpet of God as spoken of in Matthew 24:31, Revelation 1:15, Exodus 19:16-20, the Almighty will shout like a drunk man and will bring about his unusual act-Isaiah 28:21, 1 Thessalonians 4:16-17, Matthew 24:31, The Almighty will raise his chosen dead and living and transform them in an instant of time. After this short time of just over 1 minute, the Almighty God will disappear into the heavens. After this the Israeli leaders will be emboldened to nuke off the face of the earth the invading U.S. forces, Zechariah 13:8-9. And lastly as an aside, after this great Earthquake of the Almighty that effects all of the earth, next comes the meteor strikes, pulled in by Planet-X:-Revelation 16:18-21. And finally the destruction of the U.S.A.(Babylon the great whore) by the United Europe as shown in Revelation 17:16-18. The great city-nation the United States of America shall be thrown down with violence-Revelation 18:21-24, 23-´"For your merchants were the great men of the earth, for by your sorcery all the nations were deceived. 24-"And in her was found the blood of prophets and saints, and of all who were slain on the earth."
