You figure the Psalm 83 war comes before or after the Rapture? I’m leaning to after since Israel haters will not yet risk US retaliation for trying to annihilate all Jews from the mid east. Even with L4B and his regime in power, the US military and nuke arsenal is a mighty weapon. Once the Psalm 83 build up starts there’s no pretending any longer, satan’s minions will be exposed en masse.
I see similarities between the War of Gog/Magog (Ezekiel 38-39) and the prayer of Psalm 83. Thus it would place it before the rapture.
