Will the armies of the world, amassed against Jerusalem, when they see Jesus coming, attempt to fight him?

They are gathered together to make war against him:

Revelation 19:19 And I saw the beast, and the kings of the earth, and their armies, gathered together to make war against him that sat on the horse, and against his army.

The ten kings actually do make war with the Lamb:

Revelation 17:12 And the ten horns which thou sawest are ten kings, which have received no kingdom as yet; but receive power as kings one hour with the beast.

  14a These shall make war with the Lamb, and the Lamb shall overcome them:

But will the armies of the other kings of the earth do the same?

They start fighting one another:

Zechariah 14:13 And it shall come to pass in that day, that a great tumult from the LORD shall be among them; and they shall lay hold every one on the hand of his neighbour, and his hand shall rise up against the hand of his neighbour.

But when they see Jesus, will they be so terrified, that they simply stand there, paralyzed with fear?

And then die, standing on their feet?

Zechariah 14:12 And this shall be the plague wherewith the LORD will smite all the people that have fought against Jerusalem; Their flesh shall consume away while they stand upon their feet, and their eyes shall consume away in their holes, and their tongue shall consume away in their mouth.
