The seventh angel sounded his trumpet, and the kingdoms of this world—i.e. the kingdoms of the nations—suddenly became the kingdoms of God and of Christ, and he (Christ) shall reign forever and ever (Revelation 11:15). Suddenly all Heaven rejoiced, as the twenty four elders fell down upon their faces worshiping the Lord God Almighty, thanking him for taking this great power to himself and reigning (Revelation 11:16-17).
As the seventh trumpet blasted out, the nations became angry, and they came against the Jewish nation with fury (Revelation 11:18), for this was the time when the Lord promised he would return to judge the living and the dead, to give reward to his servants (the prophets and his saints). Jesus promised he would return in the glory of his Father, with his mighty angels and would reward every man according to his works (Matthew 16:27-28). In this context, he brought Rome and four other kings against the nation of the Jews, and rewarded them according to their works (Matthew 23:31-36).
This was the time of the resurrection, when all those who had died in the service of their Lord, arose to be with the Lord forever. At what point in the war this took place isn’t clear, but, judging from the 3 ½ ‘days’ of Revelation 11:11 (a prophetic day for a year) they arose from the dead cir. 3 ½ years after the beginning of the war.
As for Jesus destroying them that destroy the earth (Revelation 11:18), this concerns the nations who destroyed the Jews’ nation. The phrase ‘the earth’ (G1093) pertains to the nation of the Jews. Referring to the land of the Jews, Luke records Jesus’ Olivet Prophecy (Luke 21:20-24), saying there would be great distress in the land (G1093), the same word as earth in Revelation 11:18. Therefore, as is often the case in Scripture, the earth (G1093) refers to the land of the Jews. So Revelation 11:18 refers to the nations coming against the Jews and defeating them. However, this same Scripture show the nations will also be judged by Christ and will be destroyed, just as they had destroyed Jerusalem and the Temple:
Daniel 2:44 And in the days of these kings shall the God of heaven set up a kingdom, which shall never be destroyed: and the kingdom shall not be left to other people, but it shall break in pieces and consume all these kingdoms, and it shall stand for ever.
Through the Gospel the servants of the Lord judge and destroy all nations, not in a physical sense, but we destroy their defiant attitudes. We break them in pieces and consume them, so that little by little they become submissive to the Lord our God and his Christ (cf. Revelation 11:15)
Heaven was opened in the Temple of God, and the Ark of the Covenant was seen, and there were “lightning, and voices, and thundering, and an earthquake, and great hail” (Revelation 11:19), indicating the presence of God in all that was occurring on the earth. The Ark of the Covenant would be Jesus, for as Noah and his family were inside the ark and were saved, so we who are in Christ are saved. He is the Ark of the New Covenant who saves and protects his people throughout the judgment that occurs, as he destroys them that destroy the earth and brings in the new heavens and the new earth.
 Josephus: Wars of the Jews; 3.4.2. The kings who supported Vespasian and his son, Titus, were King Antiochus, King Agrippa, King Sohemus, and Malcus, King of Arabia, who altogether amounted to a 60,000 man fighting force, including cavalry and footmen, many of whom were archers.
