Empires don't collapse from the outside.
They collapse from within.
Three symptoms. Every time.
Financialization. A few people control all the capital. Everyone else is forced into debt. No honest way to make a living anymore.
Demographic crisis. Young people stop having children. Old people live longer. The empire runs out of workers to pay for the people who can't work.
Elite overproduction. Too many people want power. Not enough power to go around. They turn on each other. Civil war begins.
And when an empire is tearing itself apart from within it does something predictable.
It projects the chaos outward.
That is why America invaded Venezuela. That is why America is talking about Greenland, Canada, Mexico, Cuba.
That is why America attacked Iran.
Not because of strategy. Because of collapse.
