But more importantly they would have to join NATO. An attack on one NATO country is an attack on all. So California would get NATO support.
Obviously this is just a simple answer to a complex situation.
But you also have to consider the blow the U.S would take by losing California.
Losing California would be a massive hit to the overall power of the United States—economically, technologically, militarily, and culturally. It wouldn’t make the U.S. collapse overnight, but it would clearly weaken it in several major ways:
1. Economic impact (the biggest blow)
California alone has one of the largest economies in the world—comparable to countries like Germany or Japan.
It contributes roughly 14–15% of U.S. GDP.
Losing it would instantly shrink the U.S. economy by trillions of dollars.
Key industries lost: tech, entertainment, agriculture, trade.
2. Technology and innovation
The U.S. would lose Silicon Valley, the global center of tech innovation.
Companies like Apple, Google, and Meta are based there.
This would significantly reduce U.S. leadership in AI, software, and startups.
3. Military and strategic position
California is critical for U.S. military reach in the Pacific.
Major bases and ports (e.g., San Diego) support operations toward Asia.
Losing it would weaken U.S. influence in the Pacific and make logistics harder.
4. Population and workforce
California has about 39 million people.
That’s a huge chunk of the workforce, consumers, and tax base gone.
The U.S. would drop significantly in population and talent pool.
5. Agriculture and food supply
California produces a large share of U.S. fruits, vegetables, and nuts.
Food prices would likely rise.
The U.S. would become more dependent on imports.
6. Culture and global influence
The U.S. would lose Hollywood, a major driver of global media and cultural influence.
Soft power (movies, TV, music) would take a hit.
So how much weaker overall?
Not a collapse—but a major downgrade:
Still a superpower, but clearly less dominant
Likely still #1 militarily, but more constrained globally
Economy would shrink enough to narrow the gap with rivals like China
A rough way to think about it: losing California would be like the U.S. losing a top-tier country’s worth of power all at once—something no major nation could absorb without serious consequences.
If you want, I can break down what would happen politically or what a “California as its own country” scenario might look like.
