I enjoy Rush's books. I've read all them except his most recent book that just came out. Admittedly, they're a little far out, but who is to say that the second coming won't be far out. I suspect reality is far more like science fiction than our day to day lives lead us to think.
A few insights I found:
You can read this in the Vulgate (https://www.biblestudytools.com/vula/2-esdras/11.html). In v. 17, time is tempus which can mean opportunity, which could refer to term in office. The latin is singular in v. 16-17, which means it would be referring to specifically to FDR. "neither unto the half thereof" is "sed nec dimidium eius" could be more poetic in that the voice is saying nobody will come close to FDR in opportunities for the presidency. Prophecy is poetry, not prose.
It is interesting that the three short feathers were all targets of intelligence agencies: JFK, Nixon, and Trump. Between Biden's July 2024 debate and the coup that forced his announcement to not seek re-election, even Joe Biden (proposed short feather 4) had fallen out of favor with the intel agencies for his stubbornness to run even though he had a very low chance of winning after the media and DNC turned on him.
Fortunately, we won't have to wait too long to see what happens with this. Then, when all of us Christians are being shipped off to the gulags, Michael Rush can say, "HA! I told you so!"
