So, 3I/Atlas allegedly has been known for 20 years, they just didn't tell the public.
Which makes me ask: What is its purpose?
Aziz saw that it looks like a natural comet with a structure inside. He also saw a network when dmp'ing the reptilian in command.
So, it seems to be a listening post. It's here for observation of the solar system. Maybe it's even a hub for space travel, like a train station but for space ships.
But Aziz also saw that the ETs who protect Earth will attack 3I/Atlas when it's closest to Earth.
Which leads to the following question: What changed? They know about it for at least 20 years. If it's the enemy, why didn't they take it out earlier? Why did they tolerate its existence?
Side note: The attack on 3I/Atlas doesn't have to be on December 19, because if the attack stops its movement, it can't approach Earth any further. When the attack stops it, the day of the attack is when it's closest to Earth, not the other way around.
So, why do they decide to attack it now?
One possibility is that the ETs who protect Earth and the ETs who own 3I/Atlas aren't enemies before the attack. Maybe 3I/Atlas is violating a peacy treaty or truce by coming to close. Maybe the Earth ETs already know that, but they wait for it until the violation actually takes place.
On the other hand, it still makes the ETs on 3I/Atlas look stupid. How is it possible that they don't see the attack coming? Or do they know and want the attack to happen?
We are missing important parts of the bigger picture.
