God said He would show the pillars of smoke so I do not think it would be nuclear weapons for that is of people.
Nah 2:3 The shield of his mighty men is made red, the valiant men are in scarlet: the chariots shall be with flaming torches in the day of his preparation, and the fir trees shall be terribly shaken.
Nah 2:4 The chariots shall rage in the streets, they shall justle one against another in the broad ways: they shall seem like torches, they shall run like the lightnings.
This is obviously talking about vehicles with the flaming torches which are headlights, and they shall rage in the street and run like the lightnings for they are fast, and justle one against another because of tight knit traffic.
Nahum did not know to call them vehicles but he knew chariots was a form of transportation.
Isa 31:4 For thus hath the LORD spoken unto me, Like as the lion and the young lion roaring on his prey, when a multitude of shepherds is called forth against him, he will not be afraid of their voice, nor abase himself for the noise of them: so shall the LORD of hosts come down to fight for mount Zion, and for the hill thereof.
Isa 31:5 As birds flying, so will the LORD of hosts defend Jerusalem; defending also he will deliver it; and passing over he will preserve it.
This seems to be talking about the 1967 6 day war where Israeli fighter pilots paved the way to win that war and take possession of Jerusalem.
Rev 11:9 And they of the people and kindreds and tongues and nations shall see their dead bodies three days and an half, and shall not suffer their dead bodies to be put in graves.
Rev 11:10 And they that dwell upon the earth shall rejoice over them, and make merry, and shall send gifts one to another; because these two prophets tormented them that dwelt on the earth.
How can this happen without television and satellite transmission.
Dan 12:4 But thou, O Daniel, shut up the words, and seal the book, even to the time of the end: many shall run to and fro, and knowledge shall be increased.
Dan 12:8 And I heard, but I understood not: then said I, O my Lord, what shall be the end of these things?
Dan 12:9 And he said, Go thy way, Daniel: for the words are closed up and sealed till the time of the end.
Dan 12:10 Many shall be purified, and made white, and tried; but the wicked shall do wickedly: and none of the wicked shall understand; but the wise shall understand.
Daniel was told about the end time but did not understand but the saints will understand in the end time for many shall run to and fro, advanced travel, and knowledge shall be increased, advanced technology, which allows the saints to be able to see, hear, and know what is going on in the world, and how it is possible for the nations to come together for they can communicate with each other which they will change the operation of God on Earth.
The same as Jesus telling the saints that they shall hear of wars, and rumors of wars, and pestilences, and famines, and earthquakes that shall happen on different places on Earth.
And the saints shall be hated of all men on Earth.
But how would they know that without knowing what is happening on Earth which can only be by technology.
Pro 30:11 There is a generation that curseth their father, and doth not bless their mother.
Pro 30:12 There is a generation that are pure in their own eyes, and yet is not washed from their filthiness.
Pro 30:13 There is a generation, O how lofty are their eyes! and their eyelids are lifted up.
Pro 30:14 There is a generation, whose teeth are as swords, and their jaw teeth as knives, to devour the poor from off the earth, and the needy from among men.
The last generation before God ends sin on Earth which they will devour the poor from off the Earth, and the needy from among men, which can only happen at the time of technology for money is flowing like a raging river, and they can reach out farther to people to make more money, and we see that millions of dollars and billions of dollars is not enough for them, and they will heap and heap, and reap and reap, and keep and keep, which if they see a bum picking up a dime they would "bum rush" the person and take the dime and fondle it will delight and joy.
Rev 3:16 So then because thou art lukewarm, and neither cold nor hot, I will spue thee out of my mouth.
Rev 3:17 Because thou sayest, I am rich, and increased with goods, and have need of nothing; and knowest not that thou art wretched, and miserable, and poor, and blind, and naked.
The last Church age which many people claiming Christianity will join the festivities of heaping money to themselves, but the Bible says the love of money is the root of all evil for it neglects the poor and needy, and love is the fulfilling of the law.
