I remember some retired navy general recording a video feom his home about how its been a 100 year strategy to create fake enemies to empower the west and boost the military industrial complex.
He named the exaggerated communist enemy, then it will become the exagerated terrorist enemy, then eventually aliens.
Even if they are real, its likely peaceful, but will ve used as an excuse to create new weapon technology, and allow us to void all thise star war treaties we made during the cold war.
