Revelation 11
15 And the seventh angel sounded; and there were great voices in heaven, saying, The kingdoms of this world are become the kingdoms of our Lord, and of his Christ; and he shall reign for ever and ever.
The kingdoms of this world are become the kingdoms of our Lord. How do you not understand that Lord has returned and set up His kingdom on the earth. Armageddon is already over.
"are become" not "have become".
"are become" indicates a process has begun of taking away the influence that Satan has over the kingdoms of this world.
The process begins when the seventh angel sounds his trumpet and Michael and his angels cast Satan and his angels down to earth. The process will last a time/times/half time - until the day that Jesus returns.

When we read Revelation 12:12. we find two reactions...
1. them in heaven rejoice that Satan is finally meeting his end.
2. them on earth - woe, because Satan will be exerting great wrath knowing his time if is short.
Revelation 12:12
Therefore rejoice, ye heavens, and ye that dwell in them. Woe to the inhabiters of the earth and of the sea! for the devil is come down unto you, having great wrath, because he knoweth that he hath but a short time.
Now let's look at the reaction of the twenty four elders in heaven, in Revelation 11:16-17.
Revelation 11:16 And the four and twenty elders, which sat before God on their seats, fell upon their faces, and worshipped God,
17 Saying, We give thee thanks, O Lord God Almighty, which art, and wast, and art to come; because thou hast taken to thee thy great power, and hast reigned.
Are the twenty four elders in heaven not rejoicing ? Yes, they are rejoicing. The time of the end of Satan's influence over the kingdoms of this world has finally come.

Next, lets look Revelation 11:18, the twenty elders continue to reflect... on what is to take place, since Satan has been cast down to earth.
18 And the nations were angry, and thy wrath is come, and the time of the dead, that they should be judged, and that thou shouldest give reward unto thy servants the prophets, and to the saints, and them that fear thy name, small and great; and shouldest destroy them which destroy the earth.
The nations were angry about the plagues that the two witnesses had called down to earth, so during the time that Satan has left, God's wrath will take place
on earth.
While in heaven, the souls of them who have died in Christ will receive rewards for their dedication to Jesus during their lifetimes... 2Corinthians5:10.
While on earth, God's wrath will exert vengeance on the wicked men of the earth who will be carrying out destruction on earth against the great tribulation saints.
