Russia and China -along with others -will field soldiers numbering 200 million and pass over the Euphrates on their way to the holy land to make war with European forces -which will have passed over the Islamic nations (which will have acted against Europe) militarily like a whirwind -and also to make a land grab in the area.
Before that, Israel will be targeted with a major sustained attack from its neighbors.
Some of the following has also happened, some is happening, some will happen...
Zech 12:2 Behold,
I will make Jerusalem a cup of trembling unto all the people round about, when they shall be in the siege both against Judah
and against Jerusalem.
3And
in that day will I make Jerusalem a burdensome stone for all people: all that burden themselves with it shall be cut in pieces, though
all the people of the earth be gathered together against it.
4In that day, saith the LORD, I will smite every horse with astonishment, and his rider with madness: and I will open mine eyes upon the house of Judah, and will smite every horse of the people with blindness.
5And the governors of Judah shall say in their heart, The inhabitants of Jerusalem
shall be my strength in the LORD of hosts their God.
6In that day will I make the governors of Judah like an hearth of fire among the wood, and like a torch of fire in a sheaf; and they shall devour all the people round about, on the right hand and on the left: and Jerusalem shall be inhabited again in her own place, even in Jerusalem.
7The LORD also shall save the tents of Judah first, that the glory of the house of David and the glory of the inhabitants of Jerusalem do not magnify
themselves against Judah.
8In that day shall the LORD defend the inhabitants of Jerusalem; and he that is feeble among them at that day shall be as David; and the house of David
shall be as God, as the angel of the LORD before them.
9And it shall come to pass
in that day, that I will seek to destroy all the nations that come against Jerusalem.
After those things above... the forces gathered in the valley of Meggido to fight each other will turn to fight the returning Christ...
Zech 14:
2For
I will gather all nations against Jerusalem to battle; and the city shall be taken, and the houses rifled, and the women ravished; and half of the city shall go forth into captivity, and the residue of the people shall not be cut off from the city.
3Then shall the LORD go forth, and fight against those nations, as when he fought in the day of battle. 4And his feet shall stand in that day upon the mount of Olives, which is before Jerusalem on the east, and the mount of Olives shall cleave in the midst thereof toward the east and toward the west, and there shall be a very great valley; and half of the mountain shall remove toward the north, and half of it toward the south.
5And ye shall flee
to the valley of the mountains; for the valley of the mountains shall reach unto Azal: yea, ye shall flee, like as ye fled from before the earthquake in the days of Uzziah king of Judah: and the LORD my God shall come,
and all the saints with thee.
