I would agree that the Anti-Christ is not the abomination of desolation, but I don't think "The standing armies of Gog-Magog, when they are about to desolate Jerusalem, is the the abomination of desolation" either as stated in your 12/29 post at THE ANTI-CHRIST IS NOT THE ABOMINATION OF DESOLATION

since the abomination of desolation has to be set up and placed where it will stand in a holy place according to the Bible verses below:
 
Matt. 24:15-16, When ye therefore shall see the abomination of desolation, spoken of by Daniel the prophet stand in the holy place, (who so readeth let him understand:) then let them flee into the mountains."

Mark 13:14, "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:

Daniel 11:31, "And arms shall stand on his part, and they shall pollute the sanctuary of strength, and shall take away the daily sacrifice, and they shall place the abomination that maketh desolate."

Daniel 12:11, "And from the time that the daily sacrifice is taken away, and the abomination is set up, there shall be a thousand two hundred and ninety days."
