I think the mistake is that they made their power move before they'd collected the 400,000,000 guns out of private hands.
It seems pretty obvious to me that 2016 completely fucked their schedule and 2020 was absolute desperation to try to get it back on track. Clearly they have some kind of deadline that we don't know about. Maybe it's just being able to extract the last bit of value out of a dying host before the parasite finds its next victim, or maybe they see the 100 year cycle of jews wearing out their welcome coming up, or maybe they really do serve a demon god who is going to punish them severely for making him miss his window to take over this realm.
Regardless of whether or not Trump is ultimately good or bad for us or the jews, what I know is that if I was in Trump's place, and I was planning to actually do something about the jewish menace, I'd still be saying all the "greatest ally" platitudes and acting like a good goy while I got my pieces into position. Then when they're looking up at me with pleading eyes while they kneel next to the pit, and they say "But I thought you were our friend," I'd flatly reply, "Yeah, turns out I'm not."
