They both come together as a package. The Antichrist is fully-revealed in the middle of the Tribulation at the Great Tribulation (declares himself to be “God”).
However, he confirms the 7-year “peace covenant” at the beginning of the Tribulation.
Further, he divides the land of Israel - officially. That’s why I’m fairly-certain there will be a “Palestinian state”. Already recognized by the Vatican and several nations.
Well when the UN votes the Palestinian state ... I don’t see why they’ve not done it yet. They have the majority of mussie countries there.
