It's pretty self-explanatory I frankly find it hard to believe that you did not understand before. Granting that you understand now, so you can see these are all possible scenarios from best to worst:
1. Trump restores the government, the public also repents, God blesses the nation. (David scenario)
2. Trump restores the government, but the public does not repent. God preserves the nation for only a short period of time before judging them even more harshly than before. (Josiah scenario)
3. National divorce theory goes into effect. The wicked form their own governments and they alone get smote by God but America gets preserved by God. (Jeroboam scenario)
4. Jezebel seizes the government but the public goes into revolution and thrusts the wicked out or purges them entirely, God blesses the new American nation (The Athaliah and Jehoram scenario)
5. Jezebel seizes power, the public is too wicked to have a revolution or a national divorce and even worse is complicit in the wickedness and actually desires to be wicked and to provoke God, so God consumes the nationand wipes them out justly by his righteous judgment. (The Zedekiah scenario)
