Seem to me verse 1 and 2 is about destruction of the temple, not second coming.
But when ye shall see the abomination of desolation, spoken of by Daniel the prophet, standing where it ought not, (let him that readeth understand,) then let them that be in Judaea flee to the mountains: They are going to need to flee because destruction is coming, the day of vengeance has arrived
2Thessalonians 2:1 Now we beseech you, brethren, by the coming of our Lord Jesus Christ, and by our gathering together unto him,
2Thessalonians 2:2 That ye be not soon shaken in mind, or be troubled, neither by spirit, nor by word, nor by letter as from us, as that the day of Christ is at hand.
2Thessalonians 2:3 Let no man deceive you by any means: for that day shall not come, except there come a falling away first, and that man of sin be revealed, the son of perdition; What day shall not come? the day of Christ, The Lords Day, the 2nd coming, The day of vengeance, The Lords Return, The beginning of the millennium, when He shall descend as He ascended, The day He comes with clouds, the day we gather to Him, when He returns as Lord of Lords and King of Kings. the day Satan is destroyed with the Brightness of His coming,
2Thessalonians 2:4 Who opposeth and exalteth himself above all that is called God, or that is worshipped; so that he as God sitteth in the temple of God, shewing himself that he is God. Satan standing in the temple of God, Yes this temple will not have anything but sand left. It is going to be thoroughly done away with.
So yes Verses 1 and 2 are about the 2nd coming of Christ. Which is AFTER SATAN,

1Peter 4:12 Beloved, think it not strange concerning the fiery trial which is to try you, as though some strange thing happened unto you:
