"Be careful of over-rejoicing in what happened. Let us be thankful to God for this reprieve":
Uhm, one shouldn't "rejoice" at all. Even if someone asserts (and I strongly disagree) that it's permitted to vote for a "lesser evil", lesser evil is still evil, and Catholics merely TOLERATE but do not celebrate evil. If you are rejoicing in a Trump victory rather than having pulled the lever "holding your nose", with a heavy heart, realizing that it's the best we could get and the most we deserve ... then your moral compass is corrupt, and you should reflect upon it.
As always per the Hegelian dialectic being played on us, one side or another always gets a temporary reprieve, limited of course to that which is specific to the one side (while the agendas held by both sides continue marching on). So, for instance, the Left felt they had a "reprieve" under Biden, and so now the Right are hoping for a "reprieve" under Trump ... and they will indeed get one, for some of concerns that the Right generally have which are specific to them, but there's no reprieve from the inexorable forward march of the Hegelian juggernaut.
As per this cartoon here (which admirably depicts the reality of what's taking place), you get a short break while the foot that's been on your back gets lifted up and the other foot stomps down on the other side, but the whole time the juggernaut is marching forward. As you walk, you rarely have both feet on the ground at the same time.

But both sides continue pushing some common agendas forward (as they focus myopically on what divides them), in particular the enablement of the Jєωιѕн genocide to build out the "Greater Israel". So, at this time, the Hegelian controllers felt it expedient to get Trump the perception of some popular "mandate", giving Republicans the House, Senate, and Presidency, and since many of his base on the Right, the Scoffield Evangelicals, are rabidly Pro Zionist, the controllers wanted someone who could press forward with the next stage of Jєωιѕн expansion, whereas many on the Left actually opposed the Jєωιѕн genocide. Of course, all that pressure from the Left resulted in was an occasional statement by Biden made for domestic consumption (to appease that contingent of the Left), whereas in reality he was signalling Israel and Bibi to march full speed ahead (continuing to send taxper money to fund it), nevertheless, they wanted the next President to be able to move full speed ahead without being feterred by any such political concerns.
So, in this The Simpsons cartoon, Reverend Lovejoy (the one walking his dog) is Biden, the dog is Netanyahu, and Flanders is those on the Left who oppose what the dog is doing ... so the situation under the Democrat regime. Under the Republican regime, there's no pesky Flanders there questioning what you're doing so that you have to be more subtle and surreptitious about it, and you can just tell the dog openly to let 'er rip.
