This is a guy that types the URL (misspelled mind you) into google instead of the address bar while saying "I'm going to show you how to get to this website" if you need any more indication he is a smooth brain moron you're probably also a smooth brain moron.
I've seen this video a while back, so I checked it out (deagel.com FYI, not deagle.com) and it's a bunch of aerospace and military industry analysis reports. I can't find a single population projection anywhere on the site. I have to ask you OP, did you even bother to go to the site itself when doing your "research"?
So whatever, maybe they removed it. It's probably on an archive somewhere right? Well it is!
A US population projection for 2025 published in 2017: https://web.archive.org/web/20170508145728/http://www.deagel.com/country/United-States-of-America_c0001.aspx
Same report published in 2020: https://web.archive.org/web/20200419024042/http://www.deagel.com/country/United-States-of-America_c0001.aspx
Here is the last day I could find these reports published. It was published on august 23rd 2020. The next day their site is redesigned and there are no more population projection reports. https://web.archive.org/web/20200823034837/http://www.deagel.com/country/
As you can see, between their 2017 projection and 2020 projection the 2025 population goes from 65 million to 100 million. Obviously their projections are moving up because their expectations aren't being met. Considering they're defense industry analysts, I am guessing (at least I admit when I'm guessing) that they were expecting world war 3 before 2025. I suspect that this was the result of some TDS sufferer at the company who thought Trump would cause world war 3. Why they removed the numbers in 2020 when they'd been getting attention on this topic for years before that I don't know, I would guess to hide the obviousness of their incompetence at projection, the conspiritard in me wonders if maybe a company doing military and aerospace analysis has connections to intelligence and so knew the fix was in. Probably the former.
They probably still have internal population projections. I wonder what those say.
I've looked at a few videos online on this topic, they all seem to do the same thing. No research, just watching each other's videos and rephrasing what they saw without actually looking into it at all, obviously going after the conspiritard viewership for clicks. How you see some website making a projection and immediately conclude "if you don't see what they have planned for you I can't help you" is beyond me. No critical thinking whatsoever, absolutely 0 desire to do a little legwork before forming a worldview. Just see a stat, assume the website is owned by The Powers that Be™, and that they'd publish their plans to depopulate the western world, draw a whole set of conclusions about their motives from one data point, and of course, make a sensational video so as to get views. Do these people even want to be right? Do they have any desire to uncover anything at all? It would appear no.
So who is deagel.com? Well I can't find any sources searching it because I'm just inundated with bullshit like this video when I'm searching anything containing the name, but I did find this https://skeptics.stackexchange.com/questions/39282/is-this-forecast-predicting-massive-global-depopulation-until-2025-legit thread where someone managed to find a lot more information than me, and I don't want to rehash it all and pretend to take credit for it, unlike the endless conveyor belt of clickbait view simps making videos like the OP. So if you're interested you'll look through it, and if you're not interested you're just making noise on the internet and don't actually want to know the truth of anything.
Do "they" have something planned for us? Probably. But the conspirasphere's sentiment on what exactly that is changes like fashion. That's because it is fashion. I doubt anyone prominent today that claims to have the scoop on what they're planning actually has anything but a good pokerface and a plethora of gullible, paranoid idiots who have no problem forgetting what they believed would happen a year ago when it doesn't come true. Anyone taking a clear headed look at what those in charge want can come to some pretty easy conclusions: 1) they have grand plans that involve enslaving us all, 2) they have fashion of their own, 3) they're constantly playing catch up, pretending to be competent leaders, reacting to us while trying to project the illusion of omnipotence.
