In reply to your 3/12 post the fighting continues? (fivedoves.com) like you I also assume that the fallen angels will not prevail on Earth against the Lord Jesus' army of angels. So that the fallen angels do not cause more trouble, they would either have to be immediately thrown into the lake of fire with the false prophet and the beast (Antichrist) or they would to be chained up in the lowest part of hell with the other fallen angels who went into women and created a race of giants who are there awaiting the judgment of the great day according to Jude 1:6 which I assume would be the day of the great white throne judgment after 1000 years at which time all the dead men are brought up from hell and judged according to their works and whosoever was not found written in the book of life was cast into the lake of fire.
Since death and hell were also cast into the lake of fire, does that mean hell will exist no longer at that time? In which case, the fallen angels chained in the lowest part of hell who went into women and created a race of giants would be judged and tossed into the lake of fire which was created for them and the other fallen angels who didn't go into women would also end up in the lake of fire if they haven't already been put there. Interesting to note is the fact that "we" Christians are to judge angels according to 1 Corinthians 6:3 which says, "Know ye not that we shall judge angels?"
